Abstract
An integrated circuit radio transceiver and method therefor includes capacitive loop filter with selectable capacitive elements that are operable to adjust a signal level provided to a voltage controlled oscillator to control a frequency of an output signal of the oscillator. A plurality of switches are controlled by logic to define a discharge mode, a charge mode and charge sharing mode in which a plurality of capacitive elements share charge while generating the input voltage to the oscillator.
