Abstract

An electronic communications device includes a body of semiconductor material with an integrated electronic circuit, an inductive element, and a capacitive element. The capacitive element is formed by a first electrode and a second electrode positioned between the inductive element and the integrated electronic circuit. Tuning of the device circuitry is accomplished by energizing the inductive/capacitive elements, determining resonance frequency, and using a laser trimming operation to alter the structure of one or more of the first electrode, second electrode or inductive element and change the resonance frequency.
