Abstract

An additional stage for a Low Voltage Lazzaro's Winner Take All (WTA) circuit is introduced. It allows lowering the voltage supply requirements so that it can be functional in fine line CMOS technology. Electrical measurements of a prototype in CMOS 0.5µm technology verify the operation of the WTA circuit with VDD=1.5V. Simulations in PSpice and stability issues are presented as well.
