System and method for demodulating amplitude modulated signals

A system and method for demodulating amplitude modulated input signals uses two comparators and a charge pump circuit, which is positioned between the two comparators, to produce a demodulated signal of an amplitude modulated input signal. The two comparators and the charge pump circuit form a demod...

description A system and method for demodulating amplitude modulated input signals uses two comparators and a charge pump circuit, which is positioned between the two comparators, to produce a demodulated signal of an amplitude modulated input signal. The two comparators and the charge pump circuit form a demodulating unit that may be a part of an infrared remote control receiver. The first comparator converts the input signal from a waveform to a pulse form. The charge pump circuit then converts the pulse signal into an integrated signal in a triangular pulse form. The second comparator converts the integrated signal from a triangular pulse form to a rectangular pulse form to produce the demodulated signal.
