Location: Pi

Time: 15:45 - 17:30

color coded resistors

Goal of this lecture

At the end of this lecture the student should:

  1. Understand the small-signal dynamic behavior of a the intrinsic CS-stage and the CS stage between a souce and a load.

  2. Know the different ways of modeling this behavior with LTspice and SLICAP

Topics

Introduction to the CS stage

The common-source stage is considered the basic amplifier stage in CMOS technology.

Presentation

The presentation “CS stage introduction” motivates the use of the CS stage as basic amplifier stage and summerizes the relevant performance aspects and design parameters of this stage.

Design of the static and dynamic performance of a CS stage between source and load

Demonstration

The design and analysis of the static and the dynamic behavior of the CS stage will be demonstrated with the LTspice and SLiCAP simulation tools.

Download “SLiCAP-CSstage.zip” and “LTspice-CSstage.zip” for running the analysis yourself.

Please upgrade to the latest version of SLiCAP_python: Version 1.0.1 before running the CS stage script.
