摘要 |
<p>A resonator has a vibrating element (10) and at least a first (20) and a second (30) electrode, at least one of the electrodes storing an electric charge to make the device charge biased. A charge adjuster (C) can add to or reduce the stored charge. The charge adjuster can be a capacitor to reduce leakage, and or a power supply coupled by switch. It can reduce problems of stiction, and reduce power consumption, and reduce non linearity's, it enables the charge level to be adjusted before operation. A second switch can be used to ground the vibrating element.</p> |
