ABSTRACT:
An oscillation circuit comprises a resonator and frequency switching means for switching oscillating frequencies of the resonator, said frequency switching means including a capacitor and an electrical switching element in series, said electrical switching element having a small capacitance as compared to that of said capacitor and a conductive voltage larger than a peak voltage of the oscillation circuit output applied across the electrical switching element. Preferably, the electrical switching element is a diode.
