  • Wide dynamic pulse width modulation neuron circuit
    Patent number: 6756831
    Abstract: A pulse width modulation (PWM) neuron circuit. The neuron circuit includes an input control circuit, a charge/discharge circuit and an output control circuit. The input control circuit is coupled to an input voltage source and an operation voltage source. The charge/discharge circuit is coupled to the current mirror circuit. The output control circuit is being coupled to the charge/discharge circuit and the input control circuit. The input control circuit is activated and controlled by the output control circuit and a first current is generated from the input control circuit in accordance with the input voltage source and the operation voltage source. The charge/discharge circuit is charged to a predetermined voltage level in accordance with the first current from the input control circuit. The predetermined voltage level is sufficient enough to make an output of the output control circuit being changed with logic status of the output.
