Abstract
This paper describes a small signal model and analysis results for a general configuration of a gain-boosting amplifier. The simulation results generated by MATLAB matched well to HSPICE results. According to the model, the DC gain and the dominant pole approximation formulae are derived. The pole-zero movement behavior related to the model parameters are also investigated. All of above leads to a very useful model to guide the design and understanding of the gain-boosting amplifier
