Abstract

Switched capacitor (SC) circuits as discrete-time analog devices are especially suited for the signal processing tasks occurring when interfacing analog and digital systems. The major obstacle towards the use of standard CMOS technology for SC video filters is the limited speed of high-gain CMOS op-amps. This limitation can be overcome with some design ingenuity. The paper describes a switched-capacitor implementation of an antialiasing video filter that prefilters luminance and color-difference signals characterized by tight group-delay specifications as prescribed in Recommendation CCIR-601.
