Abstract

This paper describes a simple and versatile current-mode full-wave precision rectifier circuit using AD844 from Analog Devices. The proposed scheme avoids the use of closely matched resistors and matched current mirrors. The circuit is easy to design and construct from readily available low-cost components and provides excellent precision rectifier performance over a wide band and wide input voltage range. Experimental results are included.
