Abstract

The integrated circuit (1) mounted in the card has active components (2) connected to a capacitor (5) in parallel with a spiral multi-turn flat primary winding (3) on the surface of the chip. A very thin transformer core (4) passes through the centre of the primary (3) and through the printed circuit one turn secondary winding (6). The primary winding and capacitor form a tuned circuit which determines the operating frequency of the inductive link between the card and a card reading machine. The secondary winding (6) is connected to a flat conductive loop (7) which forms an antenna as it runs around the perimeter of the card.

Geïntegreerde transformator voor een contactloze identificatiekaart. Integrated transformer for a noncontact IC card. Ing. Ing. JHL Hogen Esch JHL Hogen Esch

De uitvinding betreft een transformator die deel uit maakt van een antenneconfiguratie in een electronische contactloze identiefica-tie- of Integrated Circuit (IC)-kaart, bijvoorbeeld volgens de norm ISO-7816, waarbij de secundaire spoel van de transformator een onderdeel is van de geïntegreerde schakeling in de kaart. The invention relates to a transformer which forms part of an antenna configuration in an electronic contactless identiefica-tie-or Integrated Circuit (IC) card, for example, according to the standard ISO-7816, in which the secondary coil of the transformer is a part of the integrated circuit in the card.

Integrated Circuit (IC-)kaarten, zoals bijvoorbeeld toegepast als kaart voor financiële transacties of als identificatie-pas, moeten volgens de norm ISO-7816 voldoen aan bepaalde eisen ten aanzien van afmetingen, flexibiliteit en duurzaamheid. Integrated Circuit (IC) cards, for example, used as a card for financial transactions or identification pass, according to the ISO-7816 meet certain requirements regarding size, flexibility and durability. Deze eisen zullen ook gaan gelden voor de contactloze uitvoering van deze kaarten. These requirements will also apply to the non-contact version of these cards. De normen voor deze kaarten zijn momenteel in voorbereiding. The standards for these cards are currently in preparation.

Onder andere uit "Proceedings of the Stanford Conference of Advanced Research in VLSI" 1987, pp 231-247 met de titel "Power and Communication Techniques for Physically Isolated Integrated Circuits" is een methode bekend, waarbij via een spoel op een geïntegreerd circuit een direkte contactloze inductieve koppeling tot stand wordt gebracht tussen een geïntegreerd circuit en een inductor gekoppeld aan een zend/ontvanger. Among other things, from "Proceedings of the Conference of Stanford Advanced Research in VLSI" 1987, pages 231-247, entitled "Power and Communication Techniques for Physically Isolated Integrated Circuits" a method is known, in which a direct via a coil on an integrated circuit contactless inductive coupling is established between an integrated circuit and an inductor coupled to a transmitter / receiver. Ook in het Amerikaanse patentschrift 4,857,893 van Carroll wordt een dergelijk systeem beschreven. Also in the US patent No. 4,857,893 to Carroll discloses such a system. Het nadeel van deze methode is, dat slechts weinig energie op deze wijze kan worden overgedragen en dat een zeer nauwkeurige koppeling tussen de spoel op het geïntegreerde circuit en de inductor van de zend/ontvanger noodzakelijk is vanwege de geringe afmetingen van het geïntegreerde circuit. The disadvantage of this method is that only little energy can be transferred in this way and that a very precise coupling between the coil on the integrated circuit and the inductor of the transmitter / receiver is necessary because of the small dimensions of the integrated circuit. Bij de onderhavige uitvinding maakt de spoel die is geïntegreerd in de geïntegreerde schakeling deel uit van een transformator en is dus niet rechtstreeks gekoppeld aan de inductor van de zend/ontvanger. In the present invention, the coil which is integrated in the integrated circuit is part of a transformer, and is therefore not directly coupled to the inductor of the transmitter / receiver. Om informatie-overdracht met passen die zonder batterij functioneren ook op relatief grote afstand (> 50 cm) mogelijk te maken, moet het energiegebruik van de electronische schakeling in de kaart niet alleen zeer laag zijn, maar worden er ook hoge eisen gesteld aan de antenne in de kaart. In order to adjust transmission of information that function without a battery is also at a relatively great distance (> 50 cm) as possible, the power consumption of the electronic circuit in the card must not only be very low, but high requirements are also placed on the antenna in the card. De antenne in een dergelijke kaart is veelal een afgestemde kring die is opgebouwd uit een antennespoel met een groot aantal windingen en een parallel geschakelde condensator. The antenna in such a card is often a tuned circuit which is composed of an antenna coil with a large number of turns, and a capacitor connected in parallel. Deze antenne dient niet alleen om informatie met de zend/ontvanger uit te wisselen, maar ook om energie uit het zendveld om te zetten naar de energie die nodig is om de electronische schakeling in de kaart te laten functioneren. This antenna not only serves to exchange information with the transmitter / receiver, but also to extract energy from the transmission field to convert it to the energy required to operate the electronic circuit in the card. Gestreefd wordt om de informatieoverdracht tussen de kaart en de zend/ontvanger over een zo groot mogelijke afstand plaats te laten vinden. The aim is to allow the transfer of information takes place between the card and the transmitter / receiver over as large a distance as possible. Deze afstand wordt voor een belangrijk deel bepaald door de hoogte van de spanning die door de antenne in het zendveld wordt opgewekt. This distance is largely determined by the height of the voltage which is generated by the antenna in the transmission field. In de octrooiaanvrage 9100176 van aanvraagster wordt een antenneconfigu-ratie voor contactloze identificatielabels beschreven. In the patent application 9100176 of applicant, describes a antenneconfigu-configuration for non-contact identification labels. Deze antenneconf iguratie is opgebouwd uit een antennespoel met een zeer beperkt aantal windingen, een transformator die de spanning over de antennespoel omhoog transformeert en een condensator die over de secundaire spoel van de transformator is aangesloten en die via de transformator een afgestemde resonantiekring met de antennespoel vormt. This antenneconf iguratie is composed of an antenna coil with a very limited number of turns, a transformer that transforms the voltage across the antenna coil up and a capacitor which is connected across the secondary coil of the transformer, and which forms a tuned resonant circuit with the antenna coil via the transformer . De geïntegreerde electronische schakeling in het contactloze identificatielabel wordt over de condensator en dus tevens over de secundaire spoel van de transformator aangesloten. The integrated electronic circuit in the contactless IC label is on the capacitor, and thus also connected across the secondary coil of the transformer. Deze antennecon-figuratie heeft het voordeel dat de grote antennespoel uiterst dun en buigzaam uitgevoerd kan worden, omdat: deze slechts uit een zeer beperkt aantal windingen is samengesteld. This antennecon-configuration has the advantage that the large antenna coil can be performed extremely thin and flexible, because: it only from a very limited number of windings is composed. Om een dergelijke antenneconf iguratie toe te kunnen passen in een contactloze identificatie- of IC-kaart met afmetingen en mechanische eigenschappen overeenkomstig de norm ISO-7816, moet de gehele antenneconfiguratie uiterst plat en buigzaam zijn uitgevoord. In order to be able to apply such a antenneconf iguratie in a non-contact IC card identification or with dimensions and mechanical properties in accordance with the standard ISO 7816, the entire antenna configuration has to be extremely flat and bendable out befor. Om .bij een gegeven zendveld van de zend/ontvanger de informatieoverdracht tussen de kaart en de zend/ontvanger over een zo groot moge lijke afstand mogelijk te maken, dient de transformator een hoge koppel factor en een grote parallelle zelfinductie te bezitten. In order to allow the transfer of information between the card and the transmitter / receiver over such a large distance away may .For a data transmission field of the transmitter / receiver, the transformer is required to have a high coupling factor and a large parallel inductance. Aan deze voorwaarden kan voldaan worden door de transformator van kernmateriaal met een hoge magnetische permeabiliteit te voorzien en de zelfinductie van met name de secundaire spoel hoog te maken, door deze spoel uit een groot aantal windingen samen te stellen, liet integreren van een transformator met een secundaire spoel met. These conditions can be met by providing the transformer core material having a high magnetic permeability and to make the self-inductance of, in particular, the secondary coil high, by setting this coil together from a large number of turns, showed integration of a transformer with a with secondary coil. een dergelijk groot aantal windingen in een kaart die qua afmetingen en mechanische eigenschappen aan de norm ISO-7816 voldoet, is moeilijk realiseerbaar. such a large number of turns in a card that conforms in size and mechanical properties to the standard ISO-7816, it is difficult to realize. Om aan de eisen ten aanzien van dikte en buigzaamheid te voldoen, is het niet mogelijk om een conventionele transformator, met uit koperdraad gewikkelde spoelen rond een kern, toe te passen. In order to meet the requirements in respect of thickness and flexibility, it is not possible for a conventional transformer, with coils of copper wire wound around a core, to be applied. Een dergelijke constructie is te dik en te weinig buigzaam. Such a construction is too thick and too little flexibility.

De uitvinding poogt het genoemde bezwaar op te heffen. The invention seeks to obviate the said drawback. Door de secundaire spoel van de transformator onder te brengen in de geïntegreerde schakeling voor de kaart, is het mogelijk om op een zeer klein oppervlak, slechts enkele mm2, een spoel met een groot aantal windingen te construeren. By placing the secondary coil of the transformer in the integrated circuit of the card, it is possible to construct on a very small surface area, only a few mm 2, a coil having a large number of turns. In het hart van de spoel is de geïntegreerde schakeling van een gat voorzien voor het kernmateriaal van de transformator. At the heart of the coil, the integrated circuit provided with a hole for the core material of the transformer.

In figuur 1 is een mogelijke uitvoeringsvorm van de antenneconfigu-ratie en de geïntegreerde schakeling schematisch weergegeven. Figure 1 shows a possible embodiment of the antenneconfigu-ration and the integrated circuit is schematically illustrated. De volgende onderdelen zijn in figuur 1 te onderscheiden: de geïntegreerde schakeling (1), waarbi j de el.ectronische schakeling (2) gearceerd is weergegeven; The following parts can be distinguished in Figure 1: the integrated circuit (1), j is the waarbi el.ectronische circuit (2) is shown hatched; de secundaire spoel van de transformator (3), deze maakt deel uit van de geïntegreerde schakeling en is samengesteld uit een groot aantal windingen; the secondary coil of the transformer (3), this is part of the integrated circuit and is composed of a large number of turns; - het kernmateriaal (4) van de transformator, dat een gesloten kring vormt door de primaire en do secundaire spoel van de transformator; - the core material (4) of the transformer, which constitutes a closed circuit through the primary and secondary coil of the transformer Th; - de condensator (5), die over de secundaire spoel is aangesloten en die tesamen met de secundaire spoel, de primaire spoel, de antennespoel en het kernmateriaal een afgestemde kring vormt; - the condenser (5), which is connected across the secondary coil, and which together with the secondary coil, the primary coil, the antenna coil and the core material forms a tuned circuit; - de primaire spoel (6) van de transformator, die is samengesteld uit één of slechts enkele windingen; - the primary coil (6) of the transformer, which is composed of one or a few turns; - de antennespoel (7), die is samengesteld uit één of slechts enkele windingen en die langs de rand van de kaart is (zijn) aangebracht . - the antenna coil (7), which is composed of one or a few windings, and which is along the edge of the card (are) arranged.

Figuur 2 toont de onderzijde van het geïntegreerde circuit, waarbij een gedeelte van het dragermateriaal is weggeëtst of op andere wijze is verwijderd om te voorkomen, dat een kortsluitwinding ontstaat rond het kernmateriaal. Figure 2 shows the underside of the integrated circuit, wherein a portion of the carrier material is etched away or otherwise removed in order to prevent, that a short-circuit winding around the core material. Als kernmateriaal kan gebruik worden gemaakt van ferriet of van amorf magnetisch materiaal. As a core material, use can be made of ferrite or amorphous magnetic material. Tndien ferriet wordt toegepast, kan dit geschieden in de vorm van twee U-vormige segmenten of in de vorm van een ronde of vierkante potkern, die het gehele geïntegreerde circuit omvat. Tndien ferrite is employed, it may be in the form of two U-shaped segments, or in the form of a round or square pot core, which comprises the whole integrated circuit. Dit laatste heeft als extra voordeel, dat het geïntegreerde circuit meteen tegen uitwendige invloeden wordt beschermd. The latter has the additional advantage that the integrated circuit is immediately protected against external influences. Amorf magnetisch materiaal, kan worden toegepast in de vorm van een draad, die door het gat in de geïntegreerde schakeling, rond deze geïntegreerde schakeling en één of enkele primaire winding(en) wordt gewikkeld. Amorphous magnetic material, can be used in the form of a wire, passing through the hole in the integrated circuit, around this integrated circuit, and one or a few primary winding (s) is wound. Om te voorkomen, dat het monokristal-lijne geleidende dragermateriaal, waarop liet geïntegreerde circuit is opgebouwd, gaat fungeren als een kortsluitwinding, zal dit materiaal plaatselijk moeten worden verwijderd vanaf het gat in de geïntegreerde schakeling tot aan de buitenzijde. In order to prevent that the mono crystalline conductive support material, on which an integrated circuit is allowed to build up, will act as a short-circuit winding, this material will locally have to be removed from the hole in the integrated circuit to the outside. Dit kan bijvoorbeeld geschieden, door wegetsing van dit materiaal, zoals aangegeven in figuur 2. De secundaire spoel, aangebracht, op de geïntegreerde schakeling, kan, zoals aangegeven in figuur 1, worden aangebracht naast de overige electronische componenten in deze schakeling. This may be done, for example, by wegetsing of this material, as indicated in Figure 2. The secondary coil, arranged on the integrated circuit, may, as indicated in Figure 1, may be applied in addition to the other electronic components in this circuit. Het is echter ook mogelijk deze secundaire spoel aan te brengen boven op de overige electronische componenten, waardoor ruimte kan worden bespaard en een kleinere schakeling kan worden toegepast. However, it is also possible to arrange these secondary coil on top of the other electronic components, so that space can be saved, and a smaller circuit can be used. Een groot voordeel van de opbouw van de transformator volgens deze uitvinding is verder, dat geen verbindingen in de vorm van bondingen met behulp van goud of aluminium draad van de chip of het geïntegreerde circuit naar een tweede drager nodig zijn, waardoor een relatief goedkope constructie is te realiseren. A great advantage of the construction of the transformer in accordance with the present invention is, furthermore, that any compounds in the form of bondings with the aid of gold or aluminum wire of the chip or the integrated circuit to a second carrier are necessary, so that it is a relatively inexpensive construction to realise. Dit is echter alleen mogelijk indien de condensator (5) voldoende nauwkeurig on reproduceerbaar geïntegreerd kan worden in de geïntegreerde schakeling, of indien een voorziening wordt aangebracht om de waarde van deze condensator achteraf nauwkeurig in te stellen, bijvoorbeeld via laser-trimmen of langs electronische weg. However, this is only possible if the capacitor (5) can be sufficiently accurately integrated on reproducibly in the integrated circuit, or if a provision is made to the value of this capacitor afterwards accurately set, for example, through laser-trimming, or by electronic means, .
