Concept and Simulation of a Novel Pre-Equalized CMOS Optoelectronic Integrated Receiver
-
Abstract
A novel method for enhancing the sensitivity and speed of CMOS optoelectronic integrated receivers called pre-equalization,which compensates the transferred signal at the input port of a preamplifier,is put forward.Based on 0.35μm CMOS technology,three types of pre-equalized optoelectronic integrated receivers are designed by parallel resonant loop peaking technique,third-order ladder network peaking technique,and high-pass filter peaking technique,respectively,where a fingered dual-photodiode is applied with a 40μm×40μm area,a 1.1GHz 3dB bandwidth,and a 0.95pF junction capacitance.The simulation results indicate that the sensitivity and speed of a receiver can be enhanced effectively by adding a third-order ladder network pre-equalization circuit,which achieves a -14dBm sensitivity and a 2GHz 3dB bandwidth with a bit error rate of 1e-12. -
