LOW POWER ASYNCHRONOUS PHASE DEVIATION DEMODULATION CIRCUIT FOR THE BIOLOGICAL TRANSPLANT CAPABLE OF USING AN ANALOG GLITCH ELIMINATING CIRCUIT WHICH DEMODULATES THE BROADBAND DIGITAL DATA BY SEPARATING OR COMBINING A PHASE DEVIATION DEMODULATION SIGNAL INTO AN UPPER SIDE BAND AND A LOWER SIDE BAND

摘要

PURPOSE: A low power asynchronous phase deviation demodulation circuit for the biological transplant capable of using an analog glitch eliminating circuit is provided to transmit the broadband data with the low power.;CONSTITUTION: A low power asynchronous high speed phase deviation demodulation circuit comprises a high pass filter (112), the comparators (113,114), a sensing unit (120), a clock generator (130), and a low pass filter (111). The high pass filter separates an upper side band signal from a differential signal. The comparator compares the upper side band signal with the reference signal and converts into a digital signal. The sensing unit delays the upper side band signal as the reference delay time and senses the phase change of the differential signal. The clock generator forms a symbol edge signal in each point of the sensed phase change. The low pass filter separates the lower side band signal, which forms a pair with the upper side band signal, from the differential signal.;COPYRIGHT KIPO 2013
