Abstract
An arithmetic counter circuit for high performance CMOS image sensors includes a plurality of flip-flops of a plurality of counter stages and a plurality of multiplexers of the plurality of counter stages being coupled to the plurality of flip-flops. Each of the plurality of multiplexers coupled to receive control signals including at least one of a toggle signal, a keep signal, a shift enable signal, or a mode signal. The control signals select the output of each of the plurality of multiplexers. Each of the plurality of flip-flops is coupled to be in one of a toggle state, a keep state, a reset state or a set state based on inputs received from the plurality of multiplexers. Other embodiments are described.
