Abstract
Various embodiments of charge pump circuitry configured to generate output signals having first distortion signals superimposed thereon are disclosed. Demodulator input signals are also disclosed that have second distortion signals superimposed thereon. A synchronization signal is delivered to demodulator circuitry through at least first and second integer divider circuits and to charge pump circuitry through at least the first integer divider circuitry such that the first and second distortion signals have frequencies that are integer divisions of the synchronization frequency.
