    摘要: Stepwise drivers for DC/DC converters are described herein. In one embodiment, a stepwise driver is provided to charge or discharge a gate capacitance of a power switch of a DC/DC converter. In a particular embodiment, a stepwise driver example includes multiple switching elements to sequentially switch to charge a gate capacitance of a power switch of a DC/DC converter from a first voltage to a second voltage in multiple steps. Other methods and apparatuses are also described.

    摘要: A voltage dependent capacitor to provide soft error rate tolerance in an integrated circuit is disclosed. In one embodiment, a parallel n-p voltage dependent capacitor is used to protect a node from noise. In another embodiment, an nFET-in-nWell voltage dependent capacitor is used to provide a soft error rate tolerant capacitor with reduced area.

    摘要: A method and apparatus for multi-phase transformers are described. In one embodiment, a coupled inductor topology for the multi-phase transformers comprising N primary inductors. In one embodiment, each primary inductor is coupled to one of N input nodes and a common output node. The transformer further includes N−1 secondary inductors coupled in series between one input node and the common output node. In one embodiment, the N−1 secondary inductors are arranged to couple energy from N−1 of the primary inductors to provide a common node voltage as an average of N input node voltages, wherein N is an integer greater than two. Other embodiments are described and claimed.
