Abstract
An oscillator including a resonator with at least one first tuneable element, with which a resonant frequency of the resonator can be varied. The oscillator further includes an amplifier, which provides an amplification element, connected to the resonator at a coupling position. The amplifier provides a second tuneable element, by which a complex resistance, which the amplifier provides at the coupling position, is variable in a frequency-dependent manner.
