ABSTRACT:
A circuit comprising an oscillator having a load coupled thereto by means of at least one voltage-dependent coupling element that exhibits a high impedance at relatively low voltages and low impedance at relatively higher voltages. The voltage-dependent coupling element can comprise two series connected Zener diodes connected such that the anodes of the diodes are coupled together. The voltage-dependent coupling element can also comprise a varistor.
