An amplitude limiter circuit includes an inductor and a shunt circuit. The inductor has a first terminal connected to an input node. The shunt circuit is connected to a second terminal of the inductor and also is connected to a low impedance node. If an overvoltage condition forms on the input node, the shunt circuit forms an overvoltage current path from the input node, through the inductor, through the shunt circuit and to low impedance node.
