Abstract
A transimpedance amplifier and photodiode that has a bias voltage node established at a bias voltage and a ground node/plane that connects, over a short distance as compared to the prior art, to a photodiode and a transimpedance amplifier. The photodiode is in a substrate and configured to receive and convert an optical signal to an electrical current. The photodiode has an anode terminal and a cathode terminal which is connected to the bias voltage node. One or more capacitors in or on the substrate and connected between the bias node and the ground node. The transimpedance amplifier has an input connected to the anode terminal of the photodiode and an output that presents a voltage representing the optical signal to an output path. The transimpedance amplifier and the photodiode are both electrically connected in a flip chip configuration and the ground plane creates a coplanar waveguide.
