    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: Systems and methods are disclosed for measuring signals on an integrated circuit die. In one embodiment, a reference signal is distributed to die locations proximal to the signals to be measured. The reference signal is transmitted over transport paths coupling each of the signals to be measured to the die output. The signals to be measured are transmitted over their respective transport paths and measured at the die output. The relative delay between the signals can be calculated using the reference signal measurements.
