A CMOS continuous-time NTSC-to-color-difference decoder
J.F. Parker, K.W. Current, Stephen H. Lewis · 2002
Traditional designs of NTSC video decoders are targeted for television chassis, where supply voltages of 12 V are typical and power dissipations are not a primary design concern. While these designs have used bipolar technologies, recent work has concentrated in two areas: 1) analog decoding in 5 V BiCMOS technologies, and 2) discrete-time analog decoding in CMOS technologies. However, the resulting power dissipation remains large, limiting portability that is increasingly important in consumer video applications. This paper shows that an order-of-magnitude reduction in power dissipation is achieved by decoding in CMOS with continuous-time techniques.
