Abstract :
A design procedure for video amplifiers is discussed that will 1) determine if a specific op amp can be used to satisfy the design, 2) minimize the number of stages required, and 3) determine individual stage gains required to satisfy the design. A figure of merit, based on device parameters and the specific amplifier requirements, is developed to aid the design procedure. The design procedure is directed toward practical application in that it minimizes component cost, eliminates trial and error methods, and is directly applicable to worst-case design.
