Abstract

The present disclosure relates to systems and methods for shifting the phase of a DC / DC converter to mitigate glitches. A voltage converter system is disclosed. The system has a control unit, a multiphase converter, and a measurement unit. The control unit is configured to generate one or more converter parameter adjustments from the feedback signal. The multiphase converter is configured to selectively generate an output signal at a selected voltage, and using the one or more converter parameter adjustments, one or more converter parameters are adjusted to mitigate generation of glitches in the output signal . The measurement unit is configured to measure the output signal and generate the feedback signal from the output signal.

Description

technical field [0001] The present application relates to DC / DC converters, and more particularly, to systems and methods for shifting phases of DC / DC converters to mitigate glitches. Background technique [0002] DC converters are used in various systems, such as communication systems, to adjust voltage and phase levels. A DC / DC converter takes a DC input signal and converts it to a DC output with a selected voltage level, current level and phase. [0003] A DC converter uses several phases to generate this DC output and operates at a selected frequency. Unwanted noise, known as glitches, can be generated. This unwanted noise degrades the DC output from the selected value and can negatively affect the operation of the system of which the DC converter is a part. [0004] What is needed are techniques to mitigate unwanted noise from DC converters. Contents of the invention [0005] From an aspect of the invention, a voltage converter system is disclosed, comprising: a c...
