Title: Wide dynamic range transimpedance amplifier

Abstract: An integrated circuit transimpedance amplifier for an optical receiver is formed by a bipolar process comprising fixed value resistive elements in a network to provide AGC. The resistive elements are arranged in a parallel configuration and a transistor switching network is provided to enable at least one of said elements to be isolated from a gain stage of the amplifier thereby providing a means of varying amplifier gain.
