摘要： An integrated adjustable capacitor device and method for making such a device are provided. The adjustable capacitor includes an underlying electrode, a dielectric cavity, an upper electrode, and an etch cavity for removing sacrificial material from the dielectric cavity. The surface of the device is relatively flat due to epitaxal deposition of epi polysilicon and single crystal silicon. The adjustable capacitor system is capable of undergoing CMOS processes without requiring additional steps of covering the capacitor device to protect it and then removing the covering following the CMOS processes.

摘要： A switched-mode power supply with sinusoidal current consumption includes a rectifier receiving a sinusoidal alternating voltage and having an output at which a rectified alternating voltage can be picked up. A switched controller receives the rectified alternating voltage as an input signal and supplies an output signal. A multiplier device receives and multiplies the input signal by the output signal of the switched controller and generates an output signal being supplied to the switched controller. A divider divides the output signal of the switched controller being supplied to the multiplier device by the input signal being supplied to the controller and weighted on a basis of a transfer function formed by at least two linear partial functions, and delivers a resultant signal to the multiplier device.
