Zusammenfassung:	Disclosed examples include an RF transponder circuit with signal input nodes, a rectifier circuit with a power transistor and a current mirror circuit to generate a rectifier mirror current signal, a limiter circuit with a limiter transistor and a current mirror circuit to generate a limiter mirror current signal, and a demodulator circuit to demodulate an amplitude shift keying (ASK) RF signal received at the signal input nodes according to the rectifier and limiter mirror current signal to generate a binary demodulator data signal representing the presence or absence of a threshold amount of energy in the RF signal.
