    • A novel semiconductor variable capacitor is presented. The semiconductor structure is simple and is based on a semiconductor variable capacitor with MOS compatible structure suitable for integrated circuits, which has at least three terminals, one of which is used to modulate the capacitance value between the other two terminals of the device, by increasing or decreasing its DC voltage with respect to one of the main terminals of the device. Furthermore, the present invention decouples the AC signal and the DC control voltage preventing distortion of the RF signal. The present invention describes a controllable capacitor whose capacitance value is not necessarily linear with its control voltage, but although possibly abrupt in its characteristic, is utilized to manufacture a semiconductor variable capacitor with digital control to improve its noise and linearity performance while maintaining high quality factor.

    • A novel method to operate synthetic ripple multi-phase switching power converters at constant frequency is presented. The method includes the means for sensing the current in each phase without adding extra dissipation and for balancing the currents by affecting the synthetic ripple signal to modulate the duty cycle without disturbing the overall output voltage regulation.Furthermore a method for obtaining optimum load transient response is presented. The method includes the means for simply determining the derivative of the synthetic ripple signal and for forcing maximum duty cycle until the derivative of the synthetic ripple signal reaches a certain threshold. A variant of this method improves further the load transient response by coupling an RC network to the ramp signal generated to modulate the duty cycle so as to maintain the maximum duty cycle a bit longer after the derivative of the synthetic ripple signal has reached the zero value.
