Notes/Equations
  1. AmpH1H2_Setup performs a swept input power Harmonic Balance simulation of a circuit-level amplifier and generates a dataset for subsequent use by the data-based system model AmpH1H2. The AmpH1H2_Setup extractor model is demonstrated in the example project AmpH1H2_prj.
  2. AmpH1H2_Setup can be pushed into for a view of the implementation. If necessary, the component can be copied and modified to suit individual needs.
  3. This component is capable of extracting circuit behavior at only one nominal frequency Freq. In order to characterize an amplifier over a range of frequencies, separate extractions must be performed and separate datasets generated at each frequency of interest.
  4. In order for AmpH1H2 to produce an accurate model of the circuit-level amplifier characterized via AmpH1H2_Setup, the Order parameter for AmpH1H2_Setup must be large enough to prevent aliasing of higher-order frequency components. The recommended value is 5 for mildly non-linear circuits and 11-15 for highly non-linear circuits.
  5. The linear input power sweep is defined by the parameters Pin_Start, Pin_Stop and Pin_Step are used directly by the underlying Harmonic Balance controller.
  6. The extracted ADS dataset is assigned the name of the extraction design by default.
