Abstract:
A high-frequency oscillation circuit comprising:resonance means for generating oscillation frequency signals; amplifying means having an input port for receiving the oscillation frequency signals originating from the resonance means and for amplifying the oscillation frequency signals originating from the resonance means; an inductive element having one port connected to an output port of the amplifying means and forming part of a feedback loop which feeds back output signals originating from the output port of the amplifying means into the input port; and a capacitive element having one port connected to another port of the inductive element; wherein another port of the capacitive element is grounded, the connection point of the inductive element and the capacitive element is connected to the input port of the amplifying means, and wherein the inductive element and the capacitive element compose an impedance matching means for matching the impedances of both ports of the feedback loop, the impedance matching means forming a low pass filter.
