内容記述
Nested miller compensation technique and reversed nested miller compensation technique are widely used for three-stage operational amplifiers. Both techniques employ two compensation capacitors, exploit the Miller effect to split the low frequency poles, and achieve the desired phase margin and transient response. In this paper, the conditions of transconductance to remove the right-half-plane pole in the nested miller compensation technique and the reversed nested miller compensation technique are clarified. reover, the relationships between a resonance phenomenon and load capacitance and also the conditions for preventing the resonance phenomenon in the nested miller compensation technique and the reversed nested miller compensation technique are derived. These conditions are confirmed by Mathematica and HSPICE. It was clear that the resonance phenomenon can be eliminated by using the reversed nested miller compensation technique.
