Abstract
An amplifier circuit. In one embodiment, the amplifier includes a first pair of transistors and a second pair of transistors. Each transistor in the amplifier includes a control terminal (e.g. a gate) as well as a first and second terminals. In one embodiment, the transistors are field effect transistors (FETs) and thus the first and second terminals may be either source or drain terminals. First terminals of each of the first pair of transistors may be coupled to a voltage source. The first terminal of each of the second pair of transistors is coupled to the second terminal of one of the first pair of transistors. A current source may be coupled between each of the second terminals and a voltage reference (e.g. ground plane).
