VARIABLE GAIN TRANSIMPEDANCE AMPLIFIER

摘要

Embodiments of variable gain transimpedance amplifiers are described. In an embodiment, the variable gain transimpedance amplifier may include an amplifier coupled to an adjustable gain feedback network, the adjustable gain feedback network including a selectable set of Resistor-Capacitor (RC) branches, each RC branch having one or more unit RC elements, each unit RC element being comprised of a unit resistor and a unit capacitor arranged in parallel.
