Low Voltage Semi Floating-Gate Binary to Multiple-Value and Multiple-Value to Binary Converters

Abstract

In this paper we present low-voltage multiple-valued gates. The low voltage gates may operate at a supply voltage below 250mV. We utilize the ultra low voltage CMOS logic style [1][2] to implement simple multiple-valued circuits. The radix used is determined by the supply voltage and is limited to 4 for a supply voltage equal to 250mV . Simulated data presented are valid for a ST 90nm CMOS process.
