碩士 === 中原大學 === 電子工程研究所 === 99 === 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 uses few elements, and is capable of giving amplified output and has high input impedance and low output impedance. The mentioned circuit has the resistance-matching problem. We can solve this problem by applying the precision resistors. HSPICE simulation and the experiment results are in good agreement with the theoretical analysis.
