Abstract :
Presented is a 2xVDD-enabled 90nm-CMOS TV-tuner RF frontend consisting of a power-efficient cascode-cascade-inverter LNA, a linearized C-2C attenuator using a reliably-overdriven control, dual cascode I/Q mixer drivers and an inductivepeaking gain-roll-off compensation path. In TV-GSM-interoperation mode, the circuit incooperating with a customized preselect filter exhibits a 46dB gain range, 68dB rejection at GSM-900 uplink, −5.5dBm IIP3, and 3.9dB noise figure at 26.2dB gain. The 0.28mm2 core draws 15mW.
