Abstract
The present application relates to a method for driving a sigma delta modulator. The present application relates also to a sigma delta modulator comprising at least one integrator device and one quantizer device and it relates to a readable medium having a computer program stored thereon for performing said method. The method comprises setting a sigma delta modulator to an irrational operation mode. The method comprises monitoring at least one output signal of the sigma delta modulator. The method comprises resetting the sigma delta modulator to the irrational operation mode depending on the monitored output signal.

A method, comprising:
- setting a sigma delta modulator to an irrational operation mode,
- monitoring at least one output signal of the sigma delta modulator, and
- resetting the sigma delta modulator to the irrational operation mode depending on the monitored output signal.
A sigma delta modulator, comprising:
- at least one integrator device,
- at least one quantizer device connected to the integrator device,
- at least one monitoring device configured to monitor an output signal of the sigma delta modulator, and
- at least one resetting device configured to reset the sigma delta modulator to an irrational operation mode depending on the monitored output signal of the sigma delta modulator.
