AC boosting compensation with zero cancellation for multistage amplifiers

This paper presents a high-gain wide-bandwidth multistage amplifier for sub-fV applications. This serves as an error amplifier for low-drop-out (LDO) voltage regulators. The amplifier is stabilized using an AC gain boosting scheme along with RHP zero cancellation (ACBZC). An AC multipath is added to the internal stage of the conventional three stage… CONTINUE READING
