Abstract
A linear source follower amplifier is provided with a first metal-oxide semiconductor (MOS) field effect transistor (FET) having a gate to accept an ac input signal and a source to supply an ac output signal. A second MOS FET has a gate to accept the ac input signal, a source connected to the drain of the first MOS FET. A third MOS FET has a drain connected to the source of the first MOS FET, a gate connected to the drain of the second MOS FET, and a source connected to a first reference voltage. A fourth MOS FET has a drain and a gate connected to the drain of the second MOS FET and a source connected to the first reference voltage. A current source has an input connected to a second reference voltage, and an output connected to the drain of the first MOS FET.
