Paper Abstract

A new differential topology of optical receiver which is based on a differential sensing of the output current of the photodiode is presented in this paper. The receiver proposed here is made by a P-I-N photodiode and two amplifiers, each one amplifies the current furnished by a lead of the photodiode. It is intended for digital transmission systems which require a low-pass type response. By adopting a wide band transimpedance amplifier, this topology can increase the sensitivity of the optical receiver by 3 dB as well as the output level which is increased by 6 dB, and therefore reduces the gain requirement to the transimpedance amplifier and to the main amplifier.
