Abstract
An electric circuit having a switchable feedback branch switchable between a first feedback state, in which the circuit arrangement has a frequency response that is stable with respect to an oscillation tendency, and a second feedback state, in which the circuit arrangement has a frequency response that is unstable with respect to an oscillation tendency. The circuit includes a switchable frequency response compensation circuit which during the first feedback state of the feedback branch can be controlled to an ineffective state and during the second feedback state of the feedback branch can be controlled to an effective state, and in the effective state causes such compensation of the frequency response of the circuit arrangement in the second feedback state that the circuit arrangement in the second feedback state remains stable with respect to an oscillation tendency.
