Abstract
Threshold logic design can be regarded as an alternative method of traditional logic gate design. Threshold logic can be considered as the primary logic of brain. Neurons can be considered as threshold logic gates. Each neuron fires when its activation threshold is crossed. The basic idea behind threshold logic is threshold decision principle. Threshold decision principle checks whether the weighted sum of inputs crosses a threshold and accordingly output is defined. Several implementations for threshold logic were proposed. Resistive threshold logic is a new method for threshold logic implementation. In this paper, using the concept of resistive threshold logic, a magnitude comparator is realized. LTSpiceIV and Electric VLSI Design System are the simulation tools used in this work.
