| 摘 要： | 提出了一种解决CMOS光电集成接收机灵敏度和速度问题的新方法--前均衡法,即在接收放大电路的前端对传输信号进行频率补偿,并分别采用并联谐振回路、三次阶梯网络和高通滤波器峰化技术设计了三种前均衡0.35μm CMOS光电集成接收机.其中,光电探测器选用面积为40μm×40μm的叉指型双光电二极管结构,实验测得该二极管的频率响应带宽为1.1GHz,结电容为0.95pF.对接收机的模拟结果表明:采用三次阶梯网络峰化技术的前均衡方案可有效提高光接收机的灵敏度和速度,并可实现灵敏度为-14dBm,3dB带宽为2GHz,BER为10-12的0.35μm CMOS光电集成接收机.

| 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. |
