    • An integrated, tunable capacitance device includes a semiconductor region, which is, preferably, N-doped, formed in a semiconductor body, having an insulating thick oxide region, which areally adjoins the main side of the semiconductor body, and having a thin oxide region, which, likewise, adjoins the main side and is disposed above the semiconductor region and also has a smaller layer thickness than the thick oxide region. A gate electrode is provided on the thin oxide region and terminal regions are provided in the semiconductor region. The capacitance described has a larger tuning range compared with transistor varactors. The integrated, tunable capacitance can be used, for example, in LC oscillators of integrated VCOs.
    • 集成的可调谐电容器件包括:半导体区域,优选地,N掺杂形成在半导体本体中,具有绝缘的厚氧化物区域,该半导体区域与半导体本体的主侧邻接并具有薄的氧化物区域 ,其同样邻接主侧并且设置在半导体区域的上方,并且还具有比厚氧化物区域更小的层厚度。 在薄氧化物区域上设置栅电极,在半导体区域设置端子区域。 与晶体管可变电抗器相比,所描述的电容具有较大的调谐范围。 集成的可调谐电容可用于例如集成VCO的LC振荡器。
