Abstract
An oscillator circuit includes an oscillator core having two capacitances, two inductors designed as bonding wires, and a de-attenuation amplifier coupled to the oscillator core. The inductors of the oscillator core, which is preferably embodied to be tunable, are connected to a leadframe by a respective terminal. A chip including the oscillator core and the deattentuation amplifier is configured on the leadframe. A resonance transformation circuit is preferably provided for coupling the oscillator core and the de-attenuation amplifier. The oscillator can be used in a mobile radio when there are high requirements with regard to the phase noise.
