Dual stage feedback technique for single pole feedback compensation

This paper proposes and studies the effects of a dual stage compensation technique for achieving greater than 100kHz crossover frequency of a single pole system converting from 48v to 1.2v. By placing a separate non inverting gain stage after the error amplifier, the necessary gain bandwidth of the op amp can be significantly reduced allowing for high crossover frequency and good transient response.
