Abstract:
A circuit for increasing an output direct-current level of a transimpedance amplification stage in a TIA (Trans-Impedance Amplifier) includes a transimpedance amplification stage, a differential amplification stage, a level boosting unit, and a DC-restore loop. An input terminal of the transimpedance amplification stage is used for inputting a photocurrent signal. An output terminal of the transimpedance amplification stage is directly connected to an input terminal of the differential amplification stage.
