HIGH LINEARITY FM DEMOD FOR A 4FSK WLAN TRANSCEIVER

摘要

The present invention is a fully integrated FM demodulator (400) for 4FSK demodulation in a WLAN transceiver. The features and benefits of this invention include high gain and linearity, wide frequency range, and fully integrated FM demodulation requiring no external quad network. The center frequency and gain are accurately maintained by auto-tuning. The present invention is generally applicable to FM demodulators (400).
