摘要
对国内外有关微机械可变电容的研究做了综合阐述,包括改变介质的可变电容、改变重叠面积的可变电容和改变间隔的可变电容。并对其中有代表性的电容结构进行了说明,对其获得的零偏压下的电容量值、Q值以及调节范围进行了比较。
The studies of micromachined tunable capacitors in the world are summarized. Thesecapacitors are dielectric changed variable capacitors, overlap areas changed variable capacitors andgap changed variable capacitors. Among these, the representative structures are explained. Capaci-tance under zero voltage, quality factor and tuning rage are compared.
