| In this paper it will be shown that PHD type behavioral models can be successfully utilized in the design and performance prediction of free running RF oscillators, when using an adequate extraction strategy. For that purpose, a PHD type model was extracted at two different output port impedances, from the measured response of a SiGe HBT stimulated by a set of harmonically related discrete tones. LSNA (Large Signal Network Analyzer) nonlinear measurements, at an adequate device load impedance, and different output active injections levels have been used for the extraction. Model predictions, by using the two different extraction strategies, have been compared at device and oscillator circuit level, showing the importance of the election of an appropriate output impedance for the model generation. HBT-based oscillators have been successfully designed with this model. | |
