Abstract:
1. An integrated, tunable capacitor, comprising: a semiconductor body including a semiconductor region of a first conductivity type; a first insulating region adjoining said semiconductor region of said first conductivity type; a control electrode for applying a control voltage, said, control electrode configured on said first insulating region; a first region of a second conductivity type, said first region introduced into said semiconductor body, said first region adjoining said semiconductor region, said first region including a highly doped region of said second conductivity type, said highly doped region of said second conductivity type being highly doped with respect to said first region, said highly doped region of said second conductivity type for obtaining a tuning voltage; and a well region of said second conductivity type, said well region configured in said first region of said second conductivity type, said well region configured below said highly doped region of said second conductivity type; said highly doped region of said second conductivity type embodied as a terminal region.
