Abstract:
An integrated circuit includes a degeneration network configured to improve group delay across one or more variations, wherein the degeneration network includes a transimpedance amplifier with one or more degeneration inductors. The transimpedance amplifier further includes one or more transistors, and the one or more degeneration inductors are connected after at least one emitter of the one or more transistors.
