- Provided is an error amplifier. The error amplifier includes: an amplifying unit receiving first and second input signals and amplifying a voltage difference between the received first and second input signals; a first voltage generating unit generating first and second driving voltages for driving the amplifying unit; a second voltage generating unit generating first and second body voltages to implement a body biasing method; a cascode current source including first to fourth PMOS transistors to provide a bias current to the amplifying unit and the first voltage generating unit; and an output unit outputting a signal of the voltage difference amplified by the amplifying unit, wherein the first and third PMOS transistors receive the first body voltage through a body terminal and the second and fourth PMOS transistors receive the second body voltage through a body terminal.
