Abstract
A low power BPSK demodulator having a simple architecture, compact design and reliable is provided. The BPSK demodulator includes a first branch (210) having a first mixer (212) and a first low pass filter (214), a second branch (220) coupled to the first branch at the output of the first low pass filter (214) and input of the first mixer (212) and having a second mixer (222), and a third branch (230) coupled to the second branch at the input and output of the second mixer (222) and having a third mixer (232) a second low pass filter (234) and a voltage control oscillator (236), wherein the third branch and the second branch form a charge pumped based phase lock loop that locks onto a carrier frequency of the BPSK demodulator.
