Abstract: An electrostatic drive having a plurality of mover electrodes operatively secured to a mover, and a plurality of stator electrodes operatively secured to a stator. The mover and stator are configured to move relative to each other via electrostatic force generated between the mover electrodes and the stator electrodes. The electrostatic drive includes a driver configured to place the stator electrodes in any of a number of sequential voltage states, each being defined by a combination of LO and HI voltage levels at the individual stator electrodes. Transition from one voltage state to a sequentially adjacent voltage state produces a step size of relative movement between the mover and stator.

The power supply includes a rectification circuit coupled to a main body of the power supply through an energy-storage capacitor. The main body of the power supply is provided with a reference voltage, and the setup time of the reference voltage is greater than a threshold value.

Abstract: A tunable element in the microwave frequency range is described that may include one or more tunable elements that are directly digitally controlled by a digital bus connecting a digital control circuit to each controlled element. In particular, each digital signal is filtered by a digital isolation technique so that the signal reaches the tunable elements with very low noise. The low noise digital signals are then converted to analog control voltages. The direct D/A conversion is accomplished by a special D/A converter which is manufactured as an integral part of a substrate. This D/A converter in accordance with the invention may consist of a resistor ladder or a directly digitally controlled capacitor. The direct digitally controlled capacitor may be a cantilevered type capacitor having multiple separate electrodes or sub-plates representing binary bits that may be used to control the capacitor.
