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 operating frequency range. An integrated PLL with a novel compact integrated loop filter locks a broadband dualtank VCO to a 29MHz reference. The tuner occupies less than 10mm 2 of silicon area in 0.18 m CMOS and consumes around 659mW from 3.3V/2.2V dual supply.
Abstract² a highly-integrated, ultra-low-cost Bluetooth SOC implemented in 0.11P Pm 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-ofband 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 <6% RMS DEVM. The receiver sensitivity is better than ±95.5dBm, -96.5dBm and ±89dBm for BDR, EDR2 and EDR3 modes respectively. DC current consumption for continuous TX transmission at +10dBm output power is 48mA, and for continuous RX reception at reference sensitivity level is 35mA. Total die size is 5.7mm 2 , of which 1.8mm 2 is occupied by RF, analog and PMU circuits.
