Voltage signal Max/Min finder

Abstract

In this paper, a circuit technique to realize Max/Min finder for fuzzy applications is presented. The maximum or minimum operation can be provided by setting the external control current without changing the topology, while the input signals are in the voltage forms. The proposed Max/Min finder configuration is simple and suitable for fabrication in standard CMOS technology. The circuit performance is studied using PSPICE analog simulation program. Simulation results verifying the performance of the proposed scheme are agreed with the expected values. © 2009 SICE.
