本文介绍了一种采用标准的0.7-/spl μ m CMOS技术实现的1gb /s全轨输出摆幅光接收机。接收机由一个1 k/spl ω /跨阻前置放大器和一个基于偏置逆变器链的后置放大器组成。后者执行线性和极限放大。链条的自动偏置是通过偏移容限复制电路提供的。接收器不需要外部元件或偏置电压。它设计用于相对较大的0.8 pf输入电容，并由单个5v电源供电。这些特性使电路适合商业环境。在1 Gb/s下测得灵敏度为10 /spl mu/A。完整的接收器，包括所有偏置和复制品，从5v电源消耗约100兆瓦。当由3.3 v电源供电时，最大比特率可达600 Mb/s，而功耗降至约26.5 mW。
This paper presents a 1-Gb/s optical receiver with full rail-to-rail output swing realized in a standard 0.7-/spl mu/m CMOS technology. The receiver consists of a 1-k/spl Omega/ transimpedance preamplifier followed by a postamplifier based on a biased inverter chain. The latter performs both a linear and a limiting amplification. The automatic biasing of the chain is provided through an offset tolerant replica circuit. The receiver requires no external components or biasing voltages. It is designed for a relatively large 0.8-pF input capacitance and is fed from a single 5-V power supply. These properties make the circuit suitable for a commercial environment. A sensitivity of 10 /spl mu/A was measured at 1 Gb/s. The complete receiver, including all biasing and replicas, consumes approximately 100 mW from the 5-V supply. When powered from a 3.3-V supply, a maximal bit rate of 600 Mb/s is achieved, while the power consumption is reduced to approximately 26.5 mW.
