Single-chip CMOS MSK coherent demodulator

摘要: We have fabricated a single-chip coherent demodulator for MSK (minimum shift keying), i.e. FFSK (fast frequency which is one of the most effective modulation schemes nonlinear digital radio communication systems. Carrier and clock recovery circuits are also integrated into same chip. The operates at bit rate 32 kbit/s carrier 455 kHz 5 V.
