Abstract:
A frequency-switching oscillator for switching between a plurality of oscillation frequencies, said frequency-switching oscillator comprising:a resonance system; an amplification system connected to said resonance system; and a switching member within said amplification system, said switching member being controllable to set an impedance of said amplification system; wherein said frequency-switching oscillator oscillates at a first oscillation frequency among said plurality of oscillation frequencies when said amplification system is set to a first impedance, and said frequency-switching oscillator oscillates at a second oscillation frequency among said plurality of oscillation frequencies when said amplification system is set to a second impedance; wherein said frequency-switching oscillator oscillates at a third oscillation frequency among said plurality of oscillation frequencies when said amplification system is set to a third impedance.
