Disclosed is a transimpendance amplifier comprising a single ended input terminal to receive an input signal from a photodiode and differential output terminals. A circuit coupled between the single ended input terminal and a differential output terminal may vary the gain of the transimpedance amplifier in response to a DC current component of the input signal.

Transimpedance amplifier

Disclosed is a transimpedance amplifier comprising a multi-stage amplifier, a DC current detection circuit to detect a DC current component of an input signal and a DC current removal circuit to substantially remove the DC current component of the input signal.

Transimpedance ampifier

Disclosed is a transimpedance amplifier comprising a multistage amplifier and a feedback circuit coupled between a single ended input terminal and one of a plurality of differential output terminals of the multistage amplifier. The feedback circuit may control an input voltage at the single input terminal to substantially maintain a set or predetermined transconductance between the single ended input terminal and the differential output terminals.
