| Abstract: | A powerful method for designing broadband varactor-tuned negative resistance oscillators is presented. The CAD procedure stems from a novel way of employing Hilbert transform techniques. The method is capable of realistically taking into account the decisive factors governing oscillator performance and directly processes measured large-signal data of the active device without relying on an approximate circuit model for the device. Device—circuit interactions at higher harmonic frequencies are not considered in the context. A transferred-electron oscillator design example is used to illustrate the method. |
