Embodiments of a capacitive tuning system implementing a tunable capacitive array are presented herein. The tunable capacitive array includes both scaled coarse capacitors and one or more fine capacitors. The one or more fine capacitors advantageously reduce a differential nonlinearity associated with the scaled coarse capacitors. The use of fine capacitors limits additional area requirements in an integrated circuit implementation, while improving the accuracy of the capacitive tuning system.
