Abstract
A system and method are provided for augmenting frequency tuning resolution in an L-C oscillatory circuit which comprises a source of electrical energy, and a tuned section energized by said source of electrical energy for oscillatory conduction of a resonant current therethrough. The tuned section includes an inductor portion extending in substantially looped manner between first and second connection points to define at least one turn. A primary capacitor portion is connected across at least a primary segment of the conductive member delineated by the first and second connection points. The tuned section further includes a secondary capacitor portion connected across a secondary segment of the conductive member intermediately tapped from the primary segment. The secondary capacitor portion defines a base tuning capacitance for the tuned section, which is down-converted to a fine tuning capacitance when reflected to a calibration capacitance of the primary capacitor portion for adjustable combination therewith.
