Abstract
A transimpedance amplifier (TIA) circuit comprises an input and an amplifying stage that includes N amplifiers, that generates a first signal and that is AC coupled to the input. A bias stage generates a second signal and that is DC coupled to the input. An output stage is driven by the first signal from the amplifying stage and the second signal from the bias stage.
