Design procedure and performance potential for operational amplifier using indirect compensation

A design procedure for an operational amplifier using indirect compensation is presented in this paper. Indirect compensation has inherent benefits in regards with power to speed trade-off. The technique has been seldom used in the past because a clear methodology for designing such an amplifier has not been provided. This paper develops the mathematical and analytical insight for designing an operational amplifier with this technique. The paper also provides a design strategy and an example to illustrate the use of the proposed design procedure.
