The circuit in Fig. 5.19 is to be used to provide a transimpedance gain of to the current signal coming from a photodetector. The photodetector may be modeled as a current source with an impedance of . Assuming the core amplifier has infinite input impedance, zero output impedance, and a first-order response, find its dc gain and unity-gain frequency to ensure an overall closed-loop bandwidth of 3 GHz.
