STAN tool is a patented solution, which assess the stability of RF & Microwave circuits, which is a critical step in design flow.
In comparison with other methodologies (Rollet & Nyquist Criterion, NDF ..), STAN is a unique solution that brings together all the following advantages : STAN is Fast, Rigourous, User Friendly, and ready to use with commercial CAD software.

The STAN approach calculates a single-input, single-output (SISO) transfer function for a circuit of interest linearized around a given steady state. A simulated frequency response of the linearized circuit is fitted to a rational polynomial transfer function by means of frequency-domain identification algorithm. If no poles on the right- half plane (RHP) are found, it is considered stable.

Key Features:

  • Single-node analysis
  • Multi-node analysis
  • Parametric analysis under varying load impedances
  • Parametric analysis under varying input signal power
  • Monte Carlo analysis
  • Compatible with IC, MMIC and hybrid-amplifier designs
  • Templates supplied
