Abstract: In an example embodiment, an apparatus includes an LC circuit having a capacitive circuit and an inductive circuit connected in a circuit loop. In a first mode, a switching circuit in the inductive circuit provides a charge voltage across the LC circuit and prevents oscillation of the LC circuit by opening a switch in the circuit loop. In a second mode, the switching circuit enables the oscillation of the LC circuit by closing the switch in the circuit loop. The adjustable capacitive circuit includes capacitive branch circuits configured to contribute a first amount of capacitance when enabled. For each capacitive branch circuit, an initialization circuit couples the set of capacitors to a respective reference voltage in response to the capacitive branch circuit being disabled and the switching circuit operating in the first mode.
