Overview
The AFS
single-tone
Harmonic
Balance analysis (AFS HB) is a limited-spectrum RF analysis method
thats olves
the circuit equations in the frequency domain. As with other
limited-spectrum methods, the accuracy of the HB result is a function
of the number of harmonics used in the simulation.
Benefits of HB
- Can be faster than AFS pnoise for
mild-nonlinear circuits
- Uses either a Krylov or direct solver
- Dynamic range can be better than shooting
pnoise
Target
Applications for HB
- Circuits with mildly non-linear effects
- Conventional mixers and high-Q circuits
- Frequency-dependent models
- S-parameter blocks and
transmission lines

Specifications
AFS RF
Analysis uses industry-standard netlists and models and is fully
integrated into the leading EDA design environment. It produces
standard output file formats and includes sophisticated post-processing
and analysis capabilities.
