摘要：

A fully integrated CMOS low-IF Bluetooth receiver is presented. The receiver consists of a radio frequency (RF) front end, a phase-locked loop (PLL), an active complex filter, a Gaussian frequency shift keying (GFSK) demodulator, and a frequency offset cancellation circuit. The highlights of the receiver include a low-power active complex filter with a nonconventional tuning scheme and a high-performance mixed-mode GFSK demodulator. The chip was fabricated on a 6.25-mm(2) die using TSMC 0.35-mum standard CMOS process. -82 dBm sensitivity at 1e-3 bit error rate, -10 dBm IIP3, and 15 dB noise figure were achieved in the measurements. The receiver active current is about 65 mA from a 3-V power supply.
