Abstract:
1. A transimpedance amplifier (TIA) circuit comprising: a TIA having at least one TIA input and at least one TIA output, the TIA input receiving an electrical signal generated by an optical detector in response to the optical detector converting an optical signal into the electrical signal, the TIA having an effective resistance that is adjustable, the TIA output outputting a TIA output signal; and a bandwidth adjustment (BWA) circuit electrically coupled with the TIA, the BWA circuit generating a BWA signal, and wherein the BWA circuit uses the BWA signal to produce at least one drive signal that is output to the TIA, and wherein the TIA adjusts the effective resistance of the TIA based on said at least one drive signal to control a gain and a bandwidth of the TIA circuit.
