Abstract :
To achieve an integrated solution for the 6400 bps FLEX paging receiver, we examined the direct conversion architecture and addressed two major problems that may obstruct the implementation: (1) the compensation of the DC offset, and (2) the design of a 4-level FSK demodulator at zero-IF. Simulation results show that the combination of harmonic mixers with a zero-crossing-interpolation based demodulator is a possible solution.
