Abstract
A column analog-to-digital converter and the local counting method is provided. The column analog-to-digital converter includes a plurality of analog-to-digital converters in parallel. Each of the analog-to-digital converters includes a comparator and a counting circuit. The comparator compares the ramp voltage with one of the plurality of column signals to generate a comparator output signal. The counting circuit triggers a delay line circuit of the counting circuit to generate first delay data according to the comparator output signal, re-triggers the delay line circuit to generate first re-trigger delay data according to a base clock, and compares the first delay data with the first re-trigger delay data to generate a first counting output.
