BIOMIMIC ARTIFICIAL NEURON

摘要

An artificial neuron is formed from an input subcircuit, a capacitor free leaky integrator subcircuit, and an output switching subcircuit. The input subcircuit is configured to supply a pulsed input signal. The capacitor free leaky integrator subcircuit is configured to supply a parasitic capacitance and to utilize the parasitic capacitance to provide differing time constriants for the rising and falling edges on an output signal produced in response to the pulsed input signal. The output switching subcircuit is configured to, upon receipt of a sufficient output signal from the capacitor free leaky integrator subcircuit, switch off the input subcircuit and to release a neuron firing signal (Figure 1, vin, VGR, VGA Vout).
