Abstract

This paper describes the design and development of an analog comb filter that uses switched capacitor (SC) memory circuits for an analog video processor. The fully monolithic video processor is realized by using the comb filter instead of the conventional CCD delay line. New circuit techniques improve the filter performance beyond commercial use specifications. In particular Fixed Pattern Noise (FPN) is greatly reduced to -69.4 dB which is about 14 dB lower than that of the reported data. This chip was fabricated with 0.8 /spl mu/m BiCMOS technology.
