Abstract
A cascade complementary source follower and a controlling circuit are provided. The source follower circuit includes: a source follower circuit including at least two MOS transistors, and a feedback circuit configured to clamp a voltage on a MOS transistor that provides an output voltage in the source follower circuit and to change a gate-source voltage of the MOS transistor by adjusting a bias current supplied to the MOS transistor, so that an output voltage can precisely follow an input voltage.
