Versatile Precision Full-Wave Rectifiers for Instrumentation and Measurements

This paper analyzes the performance of a family of high-quality precision full-wave rectifiers that utilize operational conveyors. The circuits have high precision, wide bandwidth, and high accuracy and are superior to the corresponding operational-amplifier (op amp)-based circuits. Using the LF351...

Description
Summary:This paper analyzes the performance of a family of high-quality precision full-wave rectifiers that utilize operational conveyors. The circuits have high precision, wide bandwidth, and high accuracy and are superior to the corresponding operational-amplifier (op amp)-based circuits. Using the LF351 op amp, they are able to rectify signals up to 100 kHz and beyond with little or no distortion. PSPICE results for the circuits are presented.
