CMOS threshold gate and networks for order statistic filtering

Abstract

Absfruct-The threshold gate is a very good candidate in the redimtion of order statistic filtering. In thls brief paper, a simple procedure iP developed to determine the dmnit parameters for a set of output-wired CMOS inverters in order to Implement threshold functions for order statistic BLtering. Weighted and nonweighted order statistie filters in either hinary or integer domalo can be easily realized in similar architectures. An incremental scheme is also proposed to construct threshold gate networks for general or multistage order statistic filters.
