In this paper, a new current mode precision rectifier circuit is proposed using a single EXCCII and two nMOS transistors. The novelty of the circuit is that it can provide all the possible rectified outputs, namely ± full wave as well as ± half wave simultaneously without any alteration of topology. Moreover, it has low input impedance and high output impedance, which is suitable for fully cascadable operation. It is suitable for a very high frequency of operation. The operating frequency is found to be 125 MHz and above. The temperature, average DC voltage output, noise, power consumption, input dynamic range (± 500 µA), Monte-Carlo and total harmonic distortion analysis are carried out to check the performance quality. The conversion of sinusoidal signal to root-mean-square circuit is also included here as an application of the proposed rectifier The proposed circuit is simulated using Cadence ORCAD PSpice simulator with 0.18 µm CMOS technology parameters. Simulation results agree well with the theoretical analysis.

本文提出了一种使用单个EXCCII和两个nMOS晶体管的新型电流模式精密整流器电路。该电路的新颖之处在于它可以同时提供所有可能的整流输出，即±全波和±半波，而无需更改拓扑。此外，它具有低输入阻抗和高输出阻抗，适合完全级联操作。它适用于非常高的操作频率。发现工作频率为125 MHz或更高。进行温度，平均直流电压输出，噪声，功耗，输入动态范围（±500 µA），蒙特卡洛和总谐波失真分析，以检查性能质量。正弦信号到均方根电路的转换也作为拟议整流器的应用包括在内。拟议电路是使用Cadence ORCAD PSpice仿真器和0.18 µm CMOS技术参数进行仿真的。仿真结果与理论分析吻合良好。
