Abstract
An integrated protection circuit for protecting a main circuit from spurious high amplitude voltage signals is provided, wherein the main circuit has a main circuit input terminal connected to an input line, and the protection circuit comprises a transistor, a resistor and a capacitor. The transistor has a first electrode connected to the input line, a second electrode connected to a common reference, and a control electrode connected to the resistor. The resistor is connected to the common reference; and the capacitor is implemented as a fringe capacitor between the input line and the control electrode or a conductive line connected to the control electrode.
