Abstract:

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 45 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/spl mu/m CMOS technology and has a tuning range of 65 to 135 ohms with a power consumption of about 34 mW.
