摘要：

A 2/4-level FSK digital demodulator for integration in a single multi-standard pager chip is presented The demodulator function is based on counting the zero crossings of the FSK signal. Frequency offset due to crystal imperfections, etc is corrected The output BER is 0.7% and 5% for input CNR of 4dB for 2-level and 4-level FSK respectively with frequency offset of 2kHz. This design uses 0.8-mu m CMOS technology and operates with power supply as low as 1 V.
