Abstract
A feedback circuit (10) for use with a feedback arrangement includes an input terminal (12) for receiving a feedback signal from an output of the feedback arrangement. An output terminal (14) is coupled to a regulating arrangement of the feedback arrangement. A sampling arrangement (16) is coupled to the input terminal for providing a delayed feedback signal. A further arrangement (18,20,22,24,26,28) is coupled to the output terminal (14) for comparing the feedback signal with the delayed feedback signal and with a predetermined reference signal, such that the further arrangement (18,20,22,24,26,28) disables the regulating arrangement if a certain relationship exists between the compared signals.
