Transconductor employing differential pair composite field effect transistors

摘要

A transconductor includes first and second differential pair compound transistors coupled between a first reference node and a common node. The compound transistors are commoned to each other at a common node. A single current source is coupled between the common node and a second reference node. In an alternate embodiment, a current turnaround circuit may be used to convert the transconductor to a single ended configuration.
