A CMOS-based multiple-input max/min circuit

Abstract

This paper presents a CMOS circuit technique for realization of the current-mode multiple-input Max/Min circuit. The maximum and minimum functions are incorporated into the same scheme with parallel processing. The design strategy is based on the use of MOS transistor operating at the edge of conduction. The proposed circuit performs a low-distortion in the transfer characteristic and is useful building block for the real-time systems. The performances of the proposed circuit were studied using the PSFICE analog simulation program. The simulation results verified the circuit performances are agreed with the expected values. © 2005 IEEE.
