Abstract: A signal processing method and device are provided to perform an arbitrary signal processing or filtering function on a continuous time signal. An input continuous time signal is successively delayed by a plurality of delay elements to produce a plurality of delayed signals. A corresponding coefficient is applied to some or all of the plurality of delayed signals to produce a plurality of weighted signals. The plurality of weighted signals are combined to produce a processed output signal. The coefficients applied to some or all of the delayed signals are set to values so as to perform a desired signal filtering or processing function of the input continuous time signal in producing the processed output signal.

Abstract: Several techniques are provided to increase the efficiency and reduce the EMI of produced by a multiphase switching voltage regulator. According to one technique, a multiphase switching voltage regulator is controlled by varying in time the duration and/or position of each switching pulse for each of a plurality of channels of the switching voltage regulator in response to one or more signals representing a state of each of a plurality of channels of the voltage regulator. According to a second technique, a method is provided for controlling a multiphase switching voltage regulator comprising operating each channel of the voltage regulator at a different frequency. The timing of the switching pulses to each channel is scheduled to avoid time-overlap of switching pulses for two or more channels.
