Abstract

Design of a new analog rank-order extractor with input expandable capability is described. An extraction for rth rank order is defined by identifying the rth largest magnitude of input variables, which is useful for fuzzy controllers and artificial neural networks. The proposed two-side search for rank-order finding greatly improves the response time. An experimental chip was fabricated using a 0.5-μm CMOS technology. The results of HSPICE post-layout simulation show that the response time of this circuit is approximately 700 ns for each rank-order operation, that the input dynamic range is about 5 μA to 30 μA, and that the resolution is 1 μA for 3.3 V supply voltage.
