Abstract :
A single-chip Bluetooth v2.1-compliant CMOS radio SoC that supports Enhanced Data Rates is implemented in standard 0.13 mum CMOS technology. All functions of a Bluetooth radio are integrated in the SoC, including RF, analog and digital parts. The RF transceiver features a polar transmitter, a two-point modulated fractional-N synthesizer, a 500 kHz IF receiver with first order low-pass analog filtering, and a DeltaSigma ADC with 74 dB dynamic range. The total SoC die area is 9.2 mm2 with only 3.0 mm2 for analog and RF circuits. The basic-rate radio power consumption is below 30 mA for both receive and transmit.
