180 1 Low Power Wideband Non-Coherent BPSK Demodulator to Align the Phase of Sideband Comparators using 1st Order Sideband Filters with Phase 180 Degree Alignment
An embodiment of the present invention relates to a broadband asynchronous BPSK demodulation method for low power and its circuit configuration. In the configuration of the BPSK demodulation circuit, the modulated signal is demultiplexed into an upper band and a lower band through a first-order high-pass filter and a first-order low-pass filter, which are carrier frequencies, and the digital output of the upper- Sideband signal and a lower-sideband signal delay unit for outputting a lower-sideband digital signal and an upper-sideband digital signal delayed by a quarter cycle of a carrier frequency while increasing the yield by minimizing jitter by minimizing jitter; Delayed from the lower band in-phase digital signal and the upper sideband portion phase by the phase difference between the digital signal as soon arranged in a 180 o to be respectively compared to the falling edge, such as a rising edge at the same time, a glitch generated by a difference of a signal small signal A data demodulator for generating a symbol edge signal from which a glitch has been removed by a diglyc filter and for demodulating data by synchronizing the delayed lower sideband positive phase digital signal with a falling edge of the symbol edge signal; And a data clock recovery unit for generating a data clock by using the delayed lower sideband positive phase digital signal and the demodulated data signal. The low power side broadband asynchronous discrete phase shifting demodulation circuit may be provided.
