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. |
