Abstract

A CMOS differential amplifier is provided comprising a current supply coupled to a first terminal of a power supply. A first CMOS transistor is provided having a first source, a first gate, and a first drain coupled to the current supply. A second CMOS transistor is also provided having a second source, a second gate, and a second drain coupled to the current supply. The first and second gates are inputs to the CMOS differential amplifier. A resistance is coupled between a second terminal of the power supply and the first source of the first transistor and the second source of the second transistor to improve common-mode and ground noise suppression.
