摘要:
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.

A pulse width modulator circuit has two self-oscillating pulse width modulators and a synchronization circuit for synchronizing the two self-oscillating pulse width modulators. It also comprises an auxiliary-signal generating circuit for generating an auxiliary signal which is coupled into the two self-oscillating pulse width modulators.
