Abstract
The present disclosure relates to an edge detection circuit configured to receive an input signal comprising one or more falling or falling edges and provide an output signal comprising pulses or spikes corresponding to the one or more rising or falling edges. The edge detection circuit comprises a passive differentiator circuit configured to receive an input and provide a differentiator output signal that that is proportional to the rate of change of the input, and a comparator circuit operably connected to a voltage source. The comparator circuit is configured to receive the differentiator output signal, compare the differentiator output signal to a threshold voltage; and output a pulse or spike signal based on the comparison to the threshold voltage.
