Analog Circuit Design is a course mostly designed for learners at all level.

Circuit design can be complex and the only way to simply it is to break it down( Divide and conquer ) .

The idea of the course is mostly to build intuition and create memory/mental models for circuits.  We believe that , the intuition we create about circuits gives the power to design/analyze and solve circuits.

The focus in this course is purely on Amplifiers : Single Stage and Multistage( Cascode and Cascade)

Some practical aspects will also be discussed which will be beneficial for Students / Beginners in Analog circuit design.

Few quick analysis techniques will be discussed . For example : Quick GM calculations , Input / Output resistance calculation , Voltage budgeting for a given supply ,  high impedance nodes  , gm reduction and increase techniques , etc

Case studies on some important circuit configuration will be discussed in detail. In each case study we will concentrate on deriving the Gain, GM and RO without using complex equation.

Please note that, this course is not designed for experts but for beginners/Students and early design engineers.

Experts or experienced engineers can review this course and refresh your design concepts.

I look forward to welcome you to this course and explore new dimension to look at circuits.  Happy Learning .
