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 wzmacniacz różniczkujący (WR), a następnie poprzez drugi układ kształtowania impulsów (SH2).
