Abstract :
In this paper a fully CMOS implementation of current-mode full-wave precision rectifier is presented. The structure is generally based on the recently presented Lazzaro´s winner-takes-all (WTA) circuit. The rectifier has been implemented using the 0.35 μm CMOS technology and its behavior verified by SPICE. The simulation results shown feasibility to process signals of frequencies up to 20 MHz.
