【 摘 要 】

References(7)A non common-node microwave chaotic Colpitts oscillator with enhanced negative resistance is introduced. Its negative resistance degradation caused by the Miller capacitance CBC is compensated with an optimum inductor load. The fundamental frequency f0 and bandwidth of this chaotic oscillation can be improved over a normal common-base or common-collector oscillators. This design also enables power consumption reduction in the oscillator.
