A 3.3-V CMOS Adaptive Analog Video Line Driver With Low Distortion Performance
نویسندگان
چکیده
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 0.5CMOS technology and has a tuning range of 70–180 with a power consumption of about 26.4 mW at 75load.

A New Fully Differential Adaptive CMOS Line Driver Using Fuzzy Controller Suitable for ADSL Modems
In this paper, a new principle for an adaptive line driver using Fuzzy logic is presented. This type of line driver can adapt its output impedance and gain, automatically to the applied load using a fuzzy logic controller (FLC). This results in automatically corrected output impedance for different cables with terminations. Also, the line driver output impedance and gain become insensitive to p...
