Abstract

Przedmiotem zgłoszenia jest dzielnik częstotliwości nośnej RFID posiadający przynajmniej dwa przerzutniki (D1, D2, D3, D4) o różnicowych wejściach i różnicowych wyjściach połączone w szereg tak, że wyjścia poprzedniego przerzutnika w szeregu (D1, D2, D3) dołączone są kolejno do wejść następnego przerzutnika w szeregu (D2, D3, D4). W dzielniku zacisk wejściowy (RF) dołączony jest jednocześnie do niezanegowanego wejścia pierwszego przerzutnika (D1) oraz poprzez układ odwracający fazę (Ri, Ti) do zanegowanego wejścia pierwszego przerzutnika (D1), a przynajmniej jedno wyjście ostatniego przerzutnika w szeregu (D4) dołączone jest do wyjścia dzielnika. Pomiędzy przynajmniej dwoma kolejnymi przerzutnikami (D1, D2), niezanegowane wyjście poprzedzającego przerzutnika (D1) dołączone jest do niezanegowanego wejścia następującego przerzutnika (D2) poprzez rezystor formujący (Rf1) i dwa inwertery połączone szeregowo (Ri1, Ti1), (Ri3, Ti3), a zanegowane wyjście poprzedzającego przerzutnika (D1) dołączone jest do zanegowanego wejścia następującego przerzutnika (D2) poprzez inny rezystor formujący (Rf2) i dwa inne inwertery połączone szeregowo (Ri2, Ti2), (Ri4, Ti4).The subject of the application is an RFID carrier frequency divider having at least two flip-flops (D1, D2, D3, D4) with differential inputs and differential outputs connected in series so that the outputs of the previous flip-flop in the series (D1, D2, D3) are connected in turn to the inputs of the next flip-flop in the series (D2, D3, D4). In the divider, the input terminal (RF) is connected simultaneously to the non-negated input of the first flip-flop (D1) and via a phase inverting circuit (Ri, Ti) to the negated input of the first flip-flop (D1), and at least one output of the last flip-flop in the series (D4) is connected to the output of the divider. Between at least two successive flip-flops (D1, D2), the non-inverted output of the preceding flip-flop (D1) is connected to the non-inverted input of the following flip-flop (D2) via a forming resistor (Rf1) and two series-connected inverters (Ri1, Ti1), (Ri3, Ti3), and the non-inverted output of the preceding flip-flop (D1) is connected to the non-inverted input of the following flip-flop (D2) via another forming resistor (Rf2) and two other series-connected inverters (Ri2, Ti2), (Ri4, Ti4).
