STAN tool is a patented solution capable of assessing the stability of RF & Microwave circuits, which is a critical step in the design flow. In comparison with other methodologies (Rollet & Nyquist Criterion, NDF …), STAN is a unique solution that brings together all the following advantages : 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.
