摘要： A switched-capacitor DC-DC converter has a reconfigurable power stage with variable gain ratio and/or interleaving regulation for low ripple voltage, fast load transient operation, variable output voltage and high efficiency. Since the power stage has multiple switches per capacitor, the converter exploits reconfigurable characteristics of the power stage for fast dynamic control and adaptive pulse control for tight and efficient voltage regulation.

摘要： A method and apparatus are disclosed for single-inductor multiple-output switching converter design. With the proposed freewheel switching control, this converter operates in a pseudo-continuous conduction mode (PCCM) and is capable of handling large load currents with a much smaller current ripple and peak inductor current, while retaining low cross regulation. It can also work in discontinuous conduction mode (DCM) for high efficiency at light loads. This design can be applied to have single or multiple outputs and for different types of DC-DC conversions.

摘要： A device and method of providing thermal compensation for integrated circuits, e.g., complementary metal-oxide semiconductor integrated circuits (“IC”) is described. The device is an IC (e.g., digital, analog, and mixed-signal circuits) with a digital voltage control system (“VCS”) having a temperature-adaptive digital DC-to-DC power converter. In one embodiment, the DC-to-DC converter includes a power stage, which converts a voltage of an input power source to a variable supply voltage, a delay-line-based temperature sensing circuit that continuously monitors temperature changes, and adjusts the frequency and process speed of the IC to compensate for any performance degradation caused by thermal effects by adjusting the voltage supplied to the IC to increase or decrease the frequency and process speed of the IC in proportion to any abnormal temperature changes in the IC.
