Abstract:
A pulse width modulation (PWM) neuron circuit, comprising:an input control circuit, being coupled to an input voltage source and an operation voltage source; a charge/discharge circuit; a current mirror circuit, being interposed between the input control circuit and the charge/discharge circuit; and an output control circuit, being coupled to the charge/discharge circuit and the input control circuit, wherein 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 being charged to a predetermined voltage level in accordance with the first current from the input control circuit, the predetermined voltage level being sufficient enough to make an output of the output control circuit being changed with logic status of the output, wherein the first current of the input control circuit being mirrored by a second current generated by the charge/discharge circuit.
