An analog current-mode multiple-input max/min circuit

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.
