Abstract :
This paper describes the analog front-end of a fully integrated CMOS TV decoder, suitable for the reception of terrestrial as well as satellite signals, based on the D2-MAC transmission system. While the video reconstruction is undertaken using DSP, the front-end subsystem incorporates many linear and non-linear analog functions, including amplitude measuring, AGC, clamping, data slicing, clock recovery and of course, A/D conversion for the MAC signal processing. The chip is fabricated in 1-μ CMOS, and operates from a single 5-V supply
