0.13μ CMOS Hybrid TV Tuner Using a Calibrated
Image and Harmonic Rejection Mixer

 

Abstract

A high image (65dB) and harmonic (70dB) rejection single conversion tuner was realized in 0.13um CMOS for hybrid analog-digital TV receivers. The different local oscillator phases required to drive the harmonic rejection mixer were obtained with an analog phase interpolator connected at the output of a multi-phase ring-oscillator. Tuner specifications include: <7dB noise figure, 45dB max gain for analog TV and 115dB gain for digital TV, >5dBm out of band IIP3, <0.8deg rms integrated phase noise, <-80dBc spurs, 1.3W power from a dual 1.8/3.3V supply and 3mm2 die area.
