Zusammenfassung:A circuit arrangement for detecting glitches on a supply voltage includes a low pass filter arrangement coupled to a supply terminal and configured to provide a filtered supply voltage. The circuit arrangement includes a first detector circuit and a second detector circuit, the first detector circuit and the second detector circuit each configured to receive the supply voltage and the filtered supply voltage, the first detector output end and the second detector output end are respectively provided with a first detection signal and a second detection signal which indicate glitches including transient positive changes and transient negative changes of the power supply voltage, and the first detector output end and the second detector output end are respectively provided with the first detection signal and the second detection signal. The circuit arrangement additionally includes a circuit arrangement output configured to provide an output signal indicative of detecting a glitch in the supply voltage based on t
