Abstract :
A CMOS power buffer suitable for video applications is discussed. The use of a high-speed push-pull output stage and a highly linear high-speed driver allows good linearity to be maintained even with very high input frequencies. Indeed, total harmonic distortions (THDs) as good as -66 and -58 dB are achieved at 0.5 and 1 MHz, respectively, with a load resistance of 75 Ω. The integrated prototype, realized using a 1.2-μm CMOS process, occupies a silicon area of 280 mils2
