摘要: A field coil signal transmission and tag power consumption measurement circuit is disclosed for use in an inductive reader system. The coupled to oscillator (20) which provides a drive differential driver (27). (27) transforms the clock into first second complementary signals (23 25). are (50) through plurality of capacitors (16 18) inductively producing output signal. differentially (50), so that each input one separate capacitor. bridge rectifier (52) opposite comprising direct current (DC) element alternating (AC) superimposed on DC element. resistance-capacitance (R-C) filter (62), (52), filtered can be decoded downstream R-C using several different decoding schemes known art.
