ABSTRACT:
A nested transimpedance amplifier (TIA) circuit includes a zero-order TIA having an input and an output. A first operational amplifier (opamp) has an input that communicates with the output of the zero-order TIA and an output. A first feedback resistance has one end that communicates with the input of the zero-order TIA and an opposite end that communicates with the output of the first opamp. A first feedback capacitance has a first end that communicates with the input of the zero-order TIA and a second end that communicates with the output of the zero-order TIA. A capacitor has one end that communicates with the input of the zero-order TIA.
