Abstract:
1. A circuit arrangement comprising: a resistive-capacitive (RC) element connected between a first supply potential line and a second supply potential line, the RC element including: a plurality of inverters connected in series and having junction points between inverters in the plurality of inverters, an input of said plurality of inverters being connected to a point between the first resistor and the first capacitor, a protection transistor having a control input, a first input, and a first output, wherein the control input is connected to the output of the plurality of inverters at a junction point, the first input is connected to the first supply potential line, and the first output is connected to the second supply potential line, and a plurality of resistors, a first input of each of the resistors being connected to a different one of the junction points between the plurality of inverters and the junction point between the inverters and the protection transistor, and a second input of each of the resistors being connected to one of the first supply potential line and the second supply potential line.
