CMOS analog neural network systems based on oscillatory neurons
(Institute of Electrical and Electronics Engineers, 1992)
This paper addresses the design of two neural network systems based on the use of pulsing neurons. Each neuron is built as a simple voltage controlled oscillator (VCO) whose control voltage makes the circuit to oscillate ...
