Rail-to-rail nMOS Amplifier

Abstract

An amplifier assembly suitable for use as a rail-to-rail amplifier is provided. The amplifier assembly includes: a first input circuit connected to a first signal input node for a first input level range; a second input circuit connected to a second signal input node for a second input level range; a load circuit coupled to the first input circuit, the second input circuit and an output node of the amplifier assembly, wherein the first input circuit includes a first auxiliary control transistor element, and a first control transistor element. The first signal input node is coupled to a control terminal of the first control transistor element and a control terminal of the first auxiliary control transistor element. A path connected in parallel to the first control transistor element includes the first auxiliary control transistor element.
