- H03B 2202/01 Reduction of undesired oscillations originated from distortion in one of the circuit elements of the oscillator
- H03B 2202/02 Reduction of undesired oscillations originated from natural noise of the circuit elements of the oscillator
- H03B 2202/03 Reduction of undesired oscillations originated from internal parasitic couplings, i.e. parasitic couplings within the oscillator itself
- H03B 2202/04 Reduction of undesired oscillations originated from outside noise or interferences, e.g. from parasitic couplings with circuit elements outside the oscillator
- H03B 2202/05 Reduction of undesired oscillations through filtering or through special resonator characteristics
- H03B 2202/06 Reduction of undesired oscillations through modification of a bias voltage, e.g. selecting the operation point of an active device
- H03B 2202/07 Reduction of undesired oscillations through a cancelling of the undesired oscillation
- H03B 2202/08 Reduction of undesired oscillations originated from the oscillator in circuit elements external to the oscillator by means associated with the oscillator
