Analytical expression of the efficiency of phantom zero compensation applied on negative-feedback amplifiers
This article reviews the phantom zero compensation technique, applied on negative-feedback (NFB) amplifiers, followed by an analysis of the important efficiency parameter, 0, of the implemented phantom zero. The effect of the efficiency on the root locus is presented, and it has been found that δ 7 will give near ideal behavior of the applied phantom zero. A reduced small signal model of the ampli
