Abstract: A spur cancellation circuit for use in a mixed signal circuit. A spur cancellation circuit includes a clock generation circuit, a flip-flop bank, and a control circuit. The clock generation circuit is configured to generate a clock signal. The flip-flop bank is coupled to the clock generation circuit, and includes a plurality of flip-flops configured to be clocked by the clock signal. The control circuit is coupled to the clock generation circuit and the flip-flop bank. The control circuit is configured to individually enable one or more of the flip-flops to change state responsive to the clock signal and consume a predetermined amount of power; and to provide a data value to be clocked into the flip-flops.
