This work is a short demonstration of a basic circuit-level simulation in ADS, the aim of this tutorial is to get familiar with several types of analysis at the circuit level that will later greatly help us to use in RFIC and MMIC design. We started with transient analysis, followed by DC, AC and S-parameters analysis.

From these analyses, particularly useful parameters can be determined, those such as noise figure, bandwidth, S parameter values, OIP3, IIP3 and many more.

The last part of this work is concerned with the solution of a task, in which according to the given values, the amplifier settings were modified and L, C values were calculated to create a scheme that complies with the requirements and from this the results were obtained.
