Abstract:
A method of pre-stressing the variable capacitor device that experiences a temporary time variant hysteresis effect is provided for electronic circuitry, which may include a mobile communication device. The method includes providing a periodic bias voltage to the variable capacitor such that the variable capacitor is maintained at least at a target stress level such that the capacitance of the variable capacitor when subject to a target bias voltage is predictable due to the time variant hysteresis effect being reduced.
