A non common-node microwave chaotic Colpitts oscillator with enhanced negative resistance is introduced. Its negative resistance degradation caused by the Miller capacitance C-BC is compensated with an optimum inductor load. The fundamental frequency f(0) 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.
