A power management unit for improving power efficiency of an electronic device. The power management unit includes a first and a second stage power regulator and a control circuitry. The first stage power regulator includes a switching regulator to efficiently adjust an input voltage based on a feedback signal. The adjusted input voltage provides the second stage power regulator that includes low dropout voltage regulators with an input voltage close to its output. Thus, power dissipation in the second stage is reduced by reducing the voltage differential between the input and desired output voltages. The second stage turns on / off power to units of the electronic device. The control circuitry generates the feedback signal based on dropout voltages of the low dropout voltages, the desired output voltage and the adjusted input voltage. The largest dropout voltage is selected and adds it to the desired output voltage to generate the feedback signal.

The invention relates to a method of forming a polyphenylene ether resin containing residual aliphatic unsaturation.

In a MIMO wireless communication system, the transformation process synthesizes the eigenmodes having a large singular value (i.e. a high effective SNR) and the eigenmodes having a small singular value (i.e. a low effective SNR). Thereby, the former eigenmodes are converted into modes having suppressed effective SNR which do not require a large number of levels of modulation, and the latter eigenmodes are converted into modes having increased effective SNR instead. In a MIMO wireless communication system for eigenmode transmission, a large communication capacity is realized without increasing the number of levels of modulation even in a communication environment capable of achieving a high SNR.
