    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.

    摘要: A method for designing and testing on-die power supply, power distribution, and noise suppression techniques for integrated circuits such as microprocessors is described. A network of time varying loads is distributed along the power supply grid to facilitate testing of new power supplies and grids and noise suppression techniques before design of the chip is completed. Several programmable current sinks are described for presenting loads according to a preferred test-waveform current. Transient, including droop detection, and static testing is easily performed using the described methods and circuitry.

    摘要: A timing circuit independently controls placement of the positive and negative edges of a periodic signal. This signal may then be used to control a wide variety of integrated circuit applications. The timing circuit includes separate programmable delay lines and a signal processor. Each delay line delays an input clock signal by a different increment of time. The signal processor then generates a timing signal from the clock signal, where the timing signal has a first edge controlled by the first delayed clock signal and a second edge controlled by the second delayed clock signal. The edges may be controlled so that the timing signal assumes different logical values for different amounts of time, thereby customizing the signal to any application. An example of one application includes using the timing signal control switching in a DC-DC converter.
