Anordning och metod vid spänningskontrollerad oscillator

摘要

The present invention relates to an oscillator having a first substrate on which a resonator circuit and an amplifier circuit are arranged. The resonator circuit has a first set of components and the amplifier circuit has an amplifier transistor and a second set of components. The first substrate includes at least two additional substrates: a second substantially insulating substrate and a third substantially semiconducting substrate. At least the amplifier transistor is arranged on the third substrate and the first and second sets of components are arranged on the second substantially insulating substrate.
