Design of an 8-bit neuron MOSFET A/D converter using subranging method

Abstract

An 8-bit subranging neuron MOSFET A/D converter circuit was designed and implemented. This neuron MOS A/D converter shows flexible operation and simple structure comparing with the common CMOS A/DC circuit. It is composed of two 4-bit A/D subconverters, 4-bit D/A subconverter, subtracter and 8-bit output latch, each subcircuit was simulated separately by using HSPICE.
