Abstract
An analog video buffer utilizes a complementary push-pull CMOS source follower video buffer with a feedback driver. The CMOS source follower provides a low impedance output node with high driving capabilities, high switching speed, and rail-to-rail linearity and the feedback driver isolates the output node from the feedback needed for the design of the video buffer to provide a transient response without ringing or overshoot.
