Abstract :
This paper presents a design and implementation of a low-power switched-capacitor filter for NTSC/PAL digital video restitution system with CCIR-601 standards. The filter which employs optimized structures including coefficient-sharing, spread-reduction, semi-offset-compensation, mismatch-shaping, double-sampling and analog multirate and multistage techniques achieves linear-phase lowpass response with 5.5-MHz bandwidth, 108 Msample/s output from 13.5 Msample/s video input and active area about 3.3 mm2 and about 80 mW power consumption. Behavior-, transistor- and layout-extracted level simulations are presented for illustrating the effectiveness of the circuit in 0.35 μm CMOS technology
