About Linear AC and Noise Simulation

The AC simulation component, in the Simulation-AC palette, performs a small-signal, linear AC analysis. As part of the analysis, the DC operating point is calculated and any nonlinear devices are linearized around that operating point. This analysis does not generate harmonics or exhibit compression. An AC simulation enables you to obtain small-signal transfer parameters, such as voltage gain, current gain, transimpedance, transadmittance, and linear noise.

Refer to the following topics for details on Linear AC and Noise simulation:

• Performing an AC Simulation has the minimum setup requirements for an AC simulation.
• Examples of AC Simulation describes in detail how to set up a basic AC simulation and how to calculate noise in ADS.
• AC Simulation Description is a brief description of the AC simulator.
• Linear Noise Simulation Description describes how noise is calculated as part of an AC simulation.
• AC Simulation Parameters provides details about the parameters available in ADS for the AC simulation controller.
