An analog line driver for video applications is presented. Utilizing a class-AB error amplifier structure, the design achieved 1.2-V peak-to-peak output swing with better than 42-dB linearity for frequencies up to 5 MHz. An adaptive tuning scheme for output impedance matching using peak detection is used to provide uniform performance across line impedance variations. The circuit is designed in AMI 0.5-μm CMOS technology and has a tuning range of 70-180 Ω with a power consumption of about 26.4 mW at 75-Ω load. [ABSTRACT FROM PUBLISHER]
