Abstract
The present disclosure provides an analog counter circuit for use in a minimal-sized circuitry. The analog counter circuit of the present disclosure can provide much higher resolution versus power consumption and layout area as compared to conventional digital counters. The analog counter circuit of the present disclosure can also provide much better bias supply management, step accuracy, multi-element step uniformity and lower supply spiking as compared to conventional analog counter architectures. The compact size of the disclosed counter circuit allows better integration of arrayed elements, such as, an array of image sensing pixels or an array of artificial neurons.
