Abstract
A transimpedance amplifier includes: a first operational amplifier; a second operational amplifier; a first resistor coupled between a first input terminal of the first operational amplifier and a first output terminal of the first operational amplifier; a second resistor coupled between the first output terminal of the first operational amplifier and a first input terminal of the second operational amplifier; and a first capacitor-resistor-capacitor (CRC) network coupled between the first input terminal of the second operational amplifier and a first output terminal of the second operational amplifier, where the first CRC network is a first reconfigurable filter that is configured to function as a first-order high-pass filter or a second-order high-pass filter based on a first control signal applied to the first CRC network.
