| 摘 要： | 在IC电路设计中,功耗问题越来越受到重视。因此提出一种工作在亚阈值电压范围内的低功耗CMOS两级运放的设计方法,并对电路的参数和性能做深入分析是很必要的。对电路进行仿真的结果显示,与传统的工作在饱和区的放大器电路相比,工作在压阈值条件下的电路功耗明显降低。

| Abstract: | In IC design,power dissipation has become more and more important.A design method of low-power CMOS two stages amplifier working in the condition of subthreshold value voltage is introdluced,and an in-depth analysis of circuit parameter and performance is made.The simulation results show that the power dissipation of amplifier circuit working in the condition of subthreshold value voltage has obvious decreases comparing with the circuit working in the condition of saturation voltage |
