Notes/Equations
- 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.
- 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.
- 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.
- 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.
- 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.
- The extracted ADS dataset is assigned the name of the extraction design by default.
