Abstract

A delta sigma modulator includes an oscillatory system having a natural frequency and an electronics and a control loop which acts upon the electronics from the oscillatory system and again upon the oscillatory system from the electronics. The control loop provides that a gain in the control loop demonstrates a peaking in a frequency range around the natural frequency of the oscillatory system.
