| 摘要 |
An integrated circuit based varactor is disclosed. The varactor comprises a substrate comprising sets of gate units each having plurality of substantially parallel gate strips. The sets of gate units are located such that the gate strips of neighbouring gate units are oriented transverse to each other. An electrically conducting gate connection layer (710) comprises gate connection units comprising a plurality of substantially parallel gate connection strips located substantially over the gate strips, and a cathode connection frame (726) around each of the gate connection units. A first electrically conductive anode layer (712) comprises first layer anode strips (716, 718) located substantially parallel to the gate connection strips and connected to alternate gate connection strips, and a first anode connection frame (724) connected to the anode strips. A second electrically conductive anode layer (714) comprises anode strips (719, 720) located substantially parallel to the gate connection strips and connected to opposite alternate gate connection strips, and a second anode connection frame (722) connected to the second layer anode strips. |
