    Abstract: The present invention generally relates to a MEMS DVC and a method for fabrication thereof. The MEMS DVC comprises a plate movable from a position spaced a first distance from an RF electrode and a second position spaced a second distance from the RF electrode that is less than the first distance. When in the second position, the plate is spaced from the RF electrode by a dielectric layer that has an RF plateau over the RF electrode. One or more secondary landing contacts and one or more plate bend contacts may be present as well to ensure that the plate obtains a good contact with the RF plateau and a consistent Cmax value can be obtained. On the figure PB contact is the plate bend contact, SL contact is the Second Landing contact and the PD electrode is the Pull Down electrode.

    Abstract: To provide a variable capacitor capable of being driven at a low voltage and yielding a stable capacitance while reducing ripple.
    The variable capacitor includes a plurality of variable capacitor elements connected in parallel with one another, the variable capacitor elements each including a fixed electrode and a movable electrode facing each other, a beam supporting the movable electrode displaceably, and a drive electrode supplied with a drive voltage to change spacing between the fixed electrode and the movable electrode. The variable capacitor further includes drive control means for sequentially applying an AC drive voltage to the drive electrodes of the variable capacitor elements with a predetermined phase difference for each element. The sum of capacitances of the variable capacitor elements is an output capacitance.

    Abstract: The present invention generally relates to a MEMS DVC. The MEMS DVC has an RF electrode and is formed above a CMOS substrate. To reduce noise in the RF signal, a poly-resistor that is connected between a waveform controller and the electrodes of the MEMS element, may be surrounded by an isolated p-well or an isolated n-well. The isolated well is coupled to an RF ground shield that is disposed between the poly-resistor and the MEMS element. Due to the presence of the isolated well that surrounds the poly-resistor, the substrate resistance does not influence the dynamic behavior of each MEMS element in the MEMS DVC and noise in the RF signal is reduced.
