ABSTRACT:
A transimpedance amplifier circuit includes a first amplifier with an input, an output and a first transconductance. A second amplifier has an input that communicates with the output of the first amplifier, an output and a second transconductance. A first resistance has one end that communicates with the input of the first amplifier. An inverter has an input that communicates with the output of the second amplifier and an output that communicates with an opposite end of the first resistance. A second resistance has one end that communicates with the input of the second amplifier and an opposite end that communicates with the output of the second amplifier. A third resistance has one end that is connected to the output of the second amplifier. A first capacitance has one end that communicates with the one end of the first resistance and an opposite end that communicates with the opposite end of the first resistance.
