First pass design is an objective that all companies try to achieve. Time to market and cost of production requirements tend to limit the number of design iterations that the product needs to go through. The stability of a power amplifier is a phenomenon that delays productions as oscillations cannot always be predicted during simulation without the right tools.

How does the STAN tool help you solve well-known problems?

  • Turnkey solution: you spend too much time analyzing the stability of your circuit to realize that it is not stable finally. You are having difficulty obtaining high-performance, stable amplifiers. STAN is the turnkey solution for you. It is a rigorous, intuitive and fast tool that gives you the information you need to obtain stable and efficient circuits.

  • Automatic algorithm to approach stability analyzes more efficiently and fast: STAN automatically searches for the best solution.

  • Linear and nonlinear stability analysis rigorously and intuitively: results of the analyses presented in the same way. At just a glance, pole-zero diagrams show the frequency of oscillation.

  • Complementary analyses to better detect the instabilities of the circuits: the parametric analyses give results according to the circuit’s parameters that allow a better optimization. It is also possible to sweep the frequency and input power to investigate the stability in the operation band. Finally, the temperature sweep helps detect instabilities as a function of the heating of the circuit.

  • Compatible with commercial simulators (ADS, AWR, Cadence-Virtuoso): stability analysis with STAN is obtained from AC / HB simulations available in commercial simulators.

The little extras you’ve been waiting for

  • It is easy to analyze the results thanks to the pole-zero diagrams that give the frequency of the instability and its evolution with different parameters of the circuit (component values, frequency and input power, temperature…).

  • Locate instability: Multi-node analyses of multi-stage circuits show you where the instability is in the circuit to apply stabilization techniques better and optimize performance.

  • Parametric and Monte Carlo analyses help with stabilization techniques: detect oscillation frequency and circuit component values to optimize stable circuit performance.
