Abstract

A transimpedance amplifier (TIA) with negative impedance compensation comprises a TIA element and a negative impedance compensator connected to the output terminal of the TIA element. The major components of the negative impedance compensator are a negative impedance element formed by a positive feedback circuit, and a compensation circuit for the parasitic capacitance at the output terminal. The negative impedance compensator changes the equivalent impedance of the output terminal from low to high with respect to the ground, and compensates the parasitic capacitance at the output terminal. Thus, an increase of both bandwidth and voltage gain is achieved.
