Versatile Precision Full-Wave Rectifier Using Current and Voltage Conveyor

摘要

This paper describes a precision full-wave rectifier of minimal configuration that is able to process both low voltage and low current signals. The behavior of the proposed rectifier is compared with the opamp based circuit by evaluating their DC value transfers and RMS errors. Furthermore, experimental measurements were performed that shown the feasibility of the new circuit to process signal up to 100 kHz and beyond with no or small distortion.
