摘　　要：A low-power,high-frequency CMOS peak detector is proposed. This detector can detect RF signal and base-band signal peaks. The circuit is designed using SMIC 0.35μm standard CMOS technology. Both theoretical calculations and post simulations show that the detection error is no more than 2% for various temperatures and processes when the input amplitude is larger than 400mV. The detection bandwidth is up to 10GHz, and its static current dissipation is less than 20μA.给出了一个低功耗、高频CMOS峰值检测电路,可以用于检测射频信号和基带信号的峰值.该电路的设计基于中芯国际0·35μm标准CMOS工艺.理论分析和后仿真结果都表明,在工艺偏差以及温度变化条件下,当输入信号幅度在400mV以上时检测的误差小于2%,检测带宽可达10GHz以上,整个检测电路的静态电流消耗低于20μA.
