1'on leave from IST, E-mail -1. Abstract This paper presents a design and implementation of a low-power Switched-Capacitor filter for NTSCFAL digital video restitution system with CCIR-601 standards. The filter which employs optimized structures including coefficient-sharing, spread-reduction, semi-offsetcompensation, mismatch-shaping, double-sampling and analog multirate & multistage techniques achieves linearphase lowpass response with 5.5-MHz bandwidth, 108 Msampleh output from 13.5 Msampleh video input and active area about 3.3 mm2 and about 80 mW power consumption. Both behavior-, transistor-and layoutextracted level simulations will be presented for illustrating the effectiveness of the circuit in 0.35 pm CMOS technology.
