    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.

    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.

    This paper presents an analog modular multiple-input Max/Min circuit, which operates in the current-mode. The maximum and minimum functions are incorporated into the same scheme with parallel processing. The realization method is suitable for fabrication using CMOS technology. The proposed circuit has a very sharp transfer characteristic and is useful building block for the real-time systems. The performances of the proposed Max/Min circuit were studied using the PSPICE analog simulation program. The simulation results verified the circuit performances are agreed with the expected values.
