A fully differential full-wave rectifier using current converyors

Abstract

This work presents a fully differential full-wave rectifier using current conveyors. Both input and output signals of the proposed rectifier can be differential or single modes. The proposed rectifier consists of two current conveyors, a positive full-wave current rectifier, a negative full-wave current rectifier and two MOS-resistors.The proposed rectifier uses all MOS structure. Simulation results from the layout in a 0.5 um MOS technology of AMI are obtained by using the level 49 model through MOSIS. The results showing the operation of the propsed rectifier at the frequencies of 1MHz and 100MHz are included.
