Abstract

A +2 dBm Bluetooth transceiver in 0.5 /spl mu/m SiGe BiCMOS consumes 22 mW at 2 V. The transmitter uses a /spl Delta//spl Sigma/ synthesizer and on-chip VCO to directly modulate the carrier and settles to 30 ppm within 180 /spl mu/s. The single low-IF I/O receiver uses a 7th-order complex IF filter with tuning, distributed AGC and digital PLL demodulation.
