Abstract
A low complexity and low power phase shift keying demodulator structure includes a digitizer, a phase-transition-independent carrier clock extractor, a binary correlater, a delay element, and a sampler. The digitizer digitizes a BPSK signal for an output waveform. The phase-transition-independent carrier clock extractor detects the phase transition on the output of the digitizer and produces a carrier clock signal. The binary correlater has correlated processes to the output signal of the digitizer and carrier clock signal obtained from the phase-transition-independent carrier clock extractor. The sampler samples the signal from the binary correlater according to the signal from the delay element in order to finish the demodulation with only a small capacitance.
