Abstract
A source follower circuit includes a first MOS transistor, a second MOS transistor, a third MOS transistor, and a feedback loop circuit. Regarding the first MOS transistor, a gate terminal receives an input signal of the source follower circuit, and a source terminal outputs an output signal of the source follower circuit. Regarding the second MOS transistor, a gate terminal is coupled to a bias voltage, a source terminal is coupled to a first reference voltage, and a drain terminal is coupled to the source terminal of the first MOS transistor. Regarding the third MOS transistor, it is a self-biased diode-connected MOS transistor with its gate terminal coupled to its drain terminal. The drain terminal of the third MOS transistor is coupled to a drain terminal of the first MOS transistor, and a source terminal of the third MOS transistor is coupled to a second reference voltage.
