Introduction

Video designs are often pressed to operate on the lowest possible rail voltages—a simple result of the trend towards lower voltage logic and the advantages of sharing supply potentials wherever possible. Video designs are further complicated by the need to accommodate the dynamic offset variation inherent in AC-coupled designs as picture content varies. Traditional op amps require relatively large amounts of output-swing headroom and are therefore impractical for AC coupling at even ...
