An ultra-low-cost Bluetooth SOC in 0.11-μm CMOS

A highly-integrated, ultra-low-cost Bluetooth SOC implemented in 0.11μm digital CMOS technology is disclosed. To reduce BOM count and cost, an integrated balun is designed for the transceiver front-end. A 4xLO based VCO is implemented to reduce LO pulling, and minimize TX out-of-band spurious in the...

Zusammenfassung:A highly-integrated, ultra-low-cost Bluetooth SOC implemented in 0.11μm digital CMOS technology is disclosed. To reduce BOM count and cost, an integrated balun is designed for the transceiver front-end. A 4xLO based VCO is implemented to reduce LO pulling, and minimize TX out-of-band spurious in the direct-conversion transmitter. The transmitter provides high output power at +10dBm and +7dBm in BDR and EDR3 modes respectively, with 1.5-kHz frequency stability and
