Abstract
A circuit arrangement for detecting a glitch on a supply voltage comprising a low pass filter arrangement coupled to a supply terminal and configured provide a filtered supply voltage. The circuit arrangement comprises a first and second detector circuit each configured to receive the supply voltage and the filtered supply voltage and configured to provide a first and second detection signal indicative of a glitch comprising a transient, positive and a transient negative change in the supply voltage at a first detector output terminal and second detector output terminal respectively. The circuit arrangement further comprises a circuit-arrangement output terminal configured to provide an output signal indicative of the detection of a glitch in the supply voltage based on the first detection signal and the second detection signal.
