Abstract

本发明提供了一种复用光通信光接收组件MON管脚的电路，通过第一箝位电路将电流镜中的PMOS管M0、M1的漏极电位保持相等，以保持整个监控动态范围的高精度。监控电流经MON管脚流出后，流入NMOS管M3，转化为M3的栅极电压后，输入第一模数转换器后转化为数字量，从而实现了电流监控功能。通过第二箝位电路，将MON管脚的电压钳制为第二箝位电路的输入电压Vcont_in，因此在跨阻放大器芯片内部通过读取MON管脚的电压Vcont_out。通过此种方式，将外部的控制信号Vcont_in复制输入到跨阻放大器内部，再通过比较器或模数转换器，将Vcont_in转化为各种控制变量。因此，就实现了MON管脚的复用。
