Abstract
A transimpedance amplifier (TIA) with integrated filtering. A capacitance is integrated into the TIA and connected to the power supply and to an internal ground of the TIA. Noise on the power supply of the transimpedance amplifier is filtered by the capacitor such that the power supply noise is reduced. The integrated capacitor also reduces noise ground. The integrated capacitor also reduces the effects of common mode noise that may be received from another circuit.
