Abstract
An optical receiver assembly that is configured to avoid the introduction of feedback in an electrical signal converted by the assembly is disclosed. In one embodiment, an optical receiver assembly is disclosed, comprising a capacitor, an optical detector provided with a power supply being mounted on a top electrode of the capacitor, and an amplifier mounted on the reference surface. The assembly further includes an isolator interposed between the reference surface and the capacitor, wherein the isolator includes a bottom layer of dielectric material that is affixed to a portion of the reference surface, and a metallic top plate that is electrically coupled both to a ground of the amplifier and to the capacitor. This configuration bootstraps the amplifier ground to the amplifier input via the photodiode top electrode of the capacitor to cancel out feedback signals present at the amplifier ground.
