Abstract
In some embodiments, a source follower circuit may include a first level shifter configured to receive an input voltage; an N-type Metal-Oxide-Semiconductor (NMOS) transistor having a gate terminal coupled to an output of the first level shifter; a second level shifter configured to receive the input voltage; a P-type Metal-Oxide-Semiconductor (PMOS) transistor having a gate terminal coupled to an output of the second level shifter and a source terminal coupled to a source terminal of the NMOS transistor; and an amplifier configured to receive the input voltage and to output a current at a node between the source terminal of the NMOS transistor and the source terminal of the PMOS transistor, wherein the current is determined based upon a difference between the input voltage and a reference voltage.
