Abstract

A highly integrated ultra-low-cost high-performance Bluetooth 3.0+EDR SoC is implemented in 0.11- md i g i t a lC M O S technology. The transceiver has a n integrated balun shared be- tween TX and RX, eliminating the need for a separate T/R switch. A4 LO-based VCO is implemented to reduce LO pulling and to minimize TX out-of-band spurious emissions. The transmitter pro- vides high output power of 10 and 7 dBm in BDR and EDR3 modes respectively, with 1.5-kHz frequency stability and 6% rms DEVM. The receiver sensitivity is 95.5, 96.5, and 89 dBm for BDR, EDR2, and EDR3 modes respectively. Total SoC DC current consumption for continuous TX transmission at 10 dBm output power is 48 mA and for continuous RX reception at reference sen- sitivity level is 35 mA. Total die size is 5.7 mm ,o fw h i c h1 . 8m m is occupied by RF, analog, and PMU circuits.
