本文提出一個用運算放大器架構之沒有負載效應的精密全波整流器電路。此電路由兩個運算放大器、兩個二極體及少數被動元件組成。本電路所需之元件數目少，且具有輸入阻抗高、輸出阻抗低以及將輸出波形放大等特性。HSPICE模擬和電路實做結果也證實其理論與分析。

This paper presents an OPA-based precision full-wave rectifier without loading effect. The circuit consists of two operational amplifiers, two diodes and few passive elements. This circuit is used few elements, and is capable of giving amplified output and has high input impedance and low output impedance. HSPICE simulation and the experiment results are in good agreement with the theoretical analysis.
