Abstract
A circuit for phase locked loop (PLL) multiple spur cancellation includes multiple spur cancellation circuits and a number of multiplexers that are coupled to respective input ports of the spur cancellation circuits. The circuit further includes a number of demultiplexers that are coupled to respective output ports of the spur cancellation circuits. Each spur cancellation circuit can cancel a spur associated with a spur source, and input nodes of the multiplexers and output nodes of the demultiplexers are coupled to different connection points of a PLL circuit.
