A source follower includes first through third switches, first and second transistors, and a first capacitor. The first switch is used to determine whether or not to couple the source of the first transistor with an input signal. The second switch is used to determine whether or not to couple a gate and a drain of the first transistor with a first voltage. A first end of the first capacitor is coupled with a first control signal, and a second end of the first capacitor is coupled to the drain of the first transistor and a gate of the second transistor. The third switch is used to determine whether to or not couple a drain of the second transistor with the first voltage, and a source of the second transistor serves as an output of the source follower.
