Abstract

Minimum and maximum circuits are basic fuzzy logic gates. Median filter is usually adopted in image noise cancellation. All of them are the special situation in a ranker finder. In this paper, a high-precision rank finder with configurable capability for maximum/minimum/median application is designed. Without modifying the circuit, this design can find the arbitrary rank among a set of input variables by setting select-signals. Moreover, the circuit schematic is regular and modular. The input dynamic range is rail-to-rail, so it can be used in fuzzy logic circuit design. This circuit has been simulated using 0.5 μm CMOS technology by HSPICE. The results show that operating speed of the circuit is 250 ns, and the resolution is 3 mV for 3.3 V supply voltage.
