<p>An oscillator includes first (1) and second (2) transistors and a parallel resonant circuit (4). The resonant circuit has first and second ends. The first end of the resonant circuit is connected to a base of the first transistor and a collector of the second transistor. The second end of the resonant circuit is connected to a base of the second transistor and a collector of the first transistor. A voltage dropping device (10) is connected between the first end of the resonant circuit and a power supply (7) for providing a voltage drop to expose the first and second transistors to driving voltages lower than a voltage of the power supply.</p>
