Abstract

Rdzeń cyfrowy znacznika RFID (DIG) zawiera dzielnik częstotliwości nośnej (FD16), którego wyjście dołączone jest do interpretera demodulacji (DI), układu przygotowania i formowania odpowiedzi (RPS) oraz dzielnika częstotliwości podnośnej (FD64), którego wyjście dołączone jest do interpretera demodulacji (DI) oraz układu przygotowania i formowania odpowiedzi (RPS), którego wyjście dołączone do wyjścia modulacji (o-Mod) rdzenia cyfrowego znacznika RFID (DIG), którego wejście demodulacji (i-Dmd) dołączone jest do wejścia sygnału zdemodulowanego interpretera demodulacji (DI), którego przynajmniej jedno wyjście dołączone jest do układu przygotowania i formowania odpowiedzi (RPS). Rdzeń cyfrowy znacznika RFID (DIG) zawiera układ obsługi protokołu (ProtH) oraz posiada wejście podtrzymania (i-VH) i wejście inicjalizacji (i-Int). Wejście podtrzymania (i-VH) dołączone jest do wejścia podtrzymania interpretera demodulacji (DI), wejście inicjalizacji (i-Int) dołączone jest do wejść inicjalizacji interpretera demodulacji (DI), układu przygotowania i formowania odpowiedzi (RPS) oraz układu obsługi protokołu (ProtH). Dwa kolejne wejścia układu obsługi protokołu (ProtH) dołączone są do dzielnika częstotliwości podnośnej (FD64) oraz interpretera demodulacji (DI), a wyjście układu obsługi protokołu (ProtH) dołączone jest do układu przygotowania i formowania odpowiedzi (RPS).The digital core of the RFID tag (DIG) includes a carrier frequency divider (FD16), the output of which is connected to a demodulation interpreter (DI), a response preparation and shaping circuit (RPS), and a subcarrier frequency divider (FD64), the output of which is connected to a demodulation interpreter (DI) and a response preparation and shaping circuit (RPS), the output of which is connected to a modulation output (o-Mod) of the digital core of the RFID tag (DIG), the demodulation input (i-Dmd) of which is connected to a demodulated signal input of the demodulation interpreter (DI), at least one output of which is connected to the response preparation and shaping circuit (RPS). The digital core of the RFID tag (DIG) includes a protocol handler (ProtH) and has a hold input (i-VH) and an initialization input (i-Int). The hold input (i-VH) is connected to the hold input of the demodulation interpreter (DI), the initialization input (i-Int) is connected to the initialization inputs of the demodulation interpreter (DI), the response preparation and shaping unit (RPS) and the protocol handler (ProtH). Two further inputs of the protocol handler (ProtH) are connected to the subcarrier frequency divider (FD64) and the demodulation interpreter (DI), and the output of the protocol handler (ProtH) is connected to the response preparation and shaping unit (RPS).
