Ulrich Rohde

With a systematic approach to the Colpitts oscillator this talk provides information for an optimized design and the resulting phase noise. Starting with the explanation about the Colpitts oscillator, invented in 1927, this presenation discussed a linear analysis based on Y-parameters, followed by S-parameter
approach, which is applicable to practically all oscillators and then move into the important time domain analysis. This allows a very reliable design, where the simulated, calculated and the measured results agree well. This detailed analysis gives a thorough insight into the design approach and results of a Colpitts oscillator. Finally the noise contribution of the tuning diodes is added. The interested attendess, having access to CAD tools can run some “experiments” by varying the component values.
