| 摘 要： | 在分析恒流源负载和带缓冲级的共源跨阻放大器性能的基础上，采用Charted 0.35 μm电可擦写编程只读存储器(electrically erasable programmable read-only memory, EEPROM)互补金属氧化物半导体(complementang metal oxide semiconductor, CMOS)工艺模拟了集成双光电二极管的光接收机前端的性能参数。交流仿真结果表明：在3.3 V电源电压下，带缓冲级跨阻放大器的光接收机具有52.1 dB的跨阻增益、5.5 GHz的带宽，增益带宽积远大于恒流源结构的光接收机。眼图仿真表明，该接收机前端可用于10 Gb/s的光纤通信系统。 |

| Abstract： | Based on the analysis of common-source transimpedance amplifier with constant-current source and buffer stage, an optical receiver front-end with integrated dual photodiodes was simulated based on Charted 0.35 μm electrically erasable programmable read-only memory (EEPROM) complementang metal oxide semiconductor (CMOS) technology. Simulation results showed that the optical receiver with buffer stage under a supply of 3.3 V has a transimpedance gain of 52.1 dB, a bandwidth of 5.5 GHz, whose gain-bandwidth product is much higher than that of the optical receiver with constant-current source. The eye diagram indicated that this receiver front-end can be used in the optical fiber communication system at 10 Gb/s. |
