Aspects include: receiving an input current having both AC component and DC component at an input terminal of the NLIFC, extracting AC component of input current, generating a number of swing voltages at a swing node using extracted AC component of the input current, transferring charge from a pull-up node to a neuron membrane potential (NP) node through an integration diode and a pull-up diode to raise a voltage at NP node over an integration capacitor gradually and the voltage at NP node shows integration value of AC component of input current, implementing leaky decay function of the neuron leaky integrate and fire circuit, detecting a timing of neuron fire using an analog comparator, resetting a neuron membrane potential level for a refractory period after neuron fire, and generating fire output signal of the NLIFC.
