Current-mode full-wave rectifier and vector summationcircuit

Abstract

A current-mode full-wave rectifier and current-mode vector summation circuit are presented. They are implemented by utilising the square-law characteristics of MOS transistors in saturation. A two-input vector summation circuit using the proposed full-wave rectifier has been fabricated in a 0.8 µm CMOS process. The experimental and simulation results confirm the feasibility of the proposed circuits.
