Description
Zapojení podle vynálezu je příkladem znázorněno na výkreeu. Integrovaný obvod (1), jehož funkce je závislá na teplotě, je připojen svými napájecími svorkami J, 8 k svorkám 2» £ zdroje napájecího napětí stabilizovaného známým způsobem pomocí Zenerovy diody 2 ® sériového odporu 6, zapojeného mezi jednu svorku 2 zdroje napájecího napětí a první vývod 2 Zenerovy diody 2· Druhý vývod 10 Zenerovy diody 2 J® připojen ke kolektoru tranzistoru 2, uvedeného do nasyceného stavu. Tranzistor 2 J® na stejném čipu, ale není využit pro současnou funkci integrovaného obvodu 1. Emitor tranzistoru 2 je připojen k druhé napájecí svorce 8 integrovaného obvodu 1' a k druhé svorce ' £' zdroje napětí.The circuit according to the invention is illustrated by way of example in the drawing. The temperature-dependent integrated circuit (1) is connected by its power terminals 18, 8 to the power supply voltage terminals 18 ', stabilized in a known manner by means of a Zener diode 2 of a series resistor 6 connected between one power supply terminal 2, and first terminal 2 of the Zener diode 2 · the second terminal 10 of the Zener diode 2 is connected to the collector of the transistor 2, saturated. The transistor 2 on the same chip, but is not used for the simultaneous operation of the integrated circuit 1. The emitter of the transistor 2 is connected to the second power terminal 8 of the integrated circuit 1 'and to the second terminal 8 of the power supply.
Stabilizované napájecí napětí integrovaného obvodu 1 je dáno součtem úbytku na Zenerově diodě 2 ® zbytkového napětí tranzistoru g. Toto zbytková napětí je závislá na teplotě čipu integrovaného obvodu 1,The stabilized supply voltage of the integrated circuit 1 is given by the sum of the drop on the Zener diode 2 ® of the residual voltage of the transistor g. This residual voltage is dependent on the chip temperature of the integrated circuit 1,
Zapojení podle vynálezu umožňuje vytvořit napájecí napětí závislá na zbytkovém napětí tranzistoru, které je přímo ovlivňováno teplotou čipu napájeného integrovaného obvodu, jehož částí tranzistor je. eeThe circuit according to the invention makes it possible to create a supply voltage dependent on the residual voltage of the transistor, which is directly influenced by the temperature of the chip of the powered integrated circuit, of which the transistor is part. ee
