ABSTRACT:
Method and system for reducing parasitic feedback and resonances in high-gain transimpedance amplifiers. In a first embodiment of the present invention, a resistive layer is implemented in the gaps of a high-gain transimpedance amplifier's metallic planes. In a second embodiment of the present invention, a resistive layer is implemented underneath a high-gain transimpedance amplifier's ground plane, vias are implemented to create contact between the resistive layer and the ground plane.
