A highly integrated ultra-low-cost high-performance Bluetooth 3.0+EDR SoC is implemented in 0.11-μm digital CMOS technology. The transceiver has an integrated balun shared between TX and RX, eliminating the need for a separate T/R switch. A 4 × LO-based VCO is implemented to reduce LO pulling and to minimize TX out-of-band spurious emissions.(More)
A 45MHz to 1002MHz direct conversion Universal TV Tuner (UTV) supports world-wide TV broadcast standards, such as ATV (NTSC, PAL, SECAM), DTV (ISDB-T, DVB-T, DVB-T2, ATSC, DTMB, DVB-C/C2), EN55020 etc. The tuner exhibits less than 5.5dB noise figure (NF), >70dB image rejection, +30dBm IIP3, +67dBm IIP2 and harmonic rejection of more than 70dB over the(More)
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(More)
