Abstract

Demodulator RFID posiada zacisk sygnału wejściowego (RF) dołączony poprzez rezystor wejściowy (Rin) do bramki pierwszego tranzystora (T1), który swoim drenem dołączony jest do źródła napięcia zasilającego (HRV), a swoim źródłem dołączony jest jednocześnie do masy układu (gnd) poprzez rezystor stałej czasowej (Rt) oraz do bramki drugiego tranzystora (T2). Drugi tranzystor (T2) swoim źródłem dołączony jest do masy układu (gnd), a swoim drenem dołączony jest jednocześnie do źródła napięcia zasilającego (HRV) poprzez drugi rezystor (R2) oraz do pierwszego wyjścia demodulatora (STR) poprzez układ kształtowania impulsów (SH1). Dren drugiego tranzystora (T2) dołączony jest także do drugiego wyjścia demodulatora (END) poprzez układ opóźniający (UO), a następnie poprzez drugi układ kształtowania impulsów (SH2).The RFID demodulator has an input signal terminal (RF) connected via an input resistor (Rin) to the gate of the first transistor (T1), whose drain is connected to the supply voltage source (HRV), and its source is also connected to the system ground (gnd) via time constant resistor (Rt) and to the gate of the second transistor (T2). The second transistor (T2) is connected to the system ground (gnd) as its source, and its drain is simultaneously connected to the supply voltage source (HRV) through the second resistor (R2) and to the first demodulator output (STR) through the pulse shaping system (SH1). . The drain of the second transistor (T2) is also connected to the second demodulator output (END) through the delay circuit (UO), and then through the second pulse shaping circuit (SH2).
