Abstract
A differential amplifier constructed from at least two metal oxide semiconductor (MOS) transistors is described. Input voltages are individually applied to the control electrodes of the transistors. The source-drain paths of the transistors are connected in series at a common junction point, and the other terminals thereof are connected to a supply voltage. The differential output voltage is taken from the aforementioned common junction point.
