A new p-i-n/HBT photoreceiver design procedure for the optimum sensitivity
최적의 감도를 얻을 수 있는 p-i-n/HBT OEIC 광수신단의 새로운 설계방법
Abstract
In this paper, an epi layer and a device structure for InP/InGaAs p-i-n/HBT OEIC is designed for a receiving frontend of high speed optical communications. A 3 stage transimpedance circuit using the p-i-n/HBT device is also designed by SPICE simulations for a high sensitivity including ISI noises at a given bit rate. Our simulations show that the Personick's assumption which is not commonly satisfied have estimated a photoreceiver sensitivity too high, so thus we have to also consider ISI noises in OCIC receiver designs.
