The present disclosure relates to circuits and methods for improving the performance of plural DC-DC voltage converters.

Synchronization of plural DC-DC voltage converters

In an integrated circuit including a first multibit digital-to-analog converter and a second multibit digital-to-analog converter, a calibration circuit is provided which is shared between the first and second digital-to-analog converters.

Integrated circuit comprising a plurality of digital-to-analog converters, sigma-delta modulator circuit, and method of calibrating a plurality of multibit digital-to-analog converters

A digital/analog converter comprises a converter array comprised of a plurality of converter cells and a device for self-calibration of the converter cells. The device for self-calibration comprises at least one reference cell with a reference value and a control device for controlling a calibration process. The control device calibrates successively, within a respective calibration period, respective of the converter cells to values corresponding to the reference value and adjusts respective calibration periods for a calibration cycle, within which the converter cells are to be calibrated. At least two different of the respective calibration periods differ within at least two calibration cycles.
