Explore transconductance gm across linear, subthreshold, and saturation regions, deriving gm expressions, and learning when to apply each equation based on which parameter is held constant.
Learn how a cascade of common drain, common gate, and common drain stages creates a high input, low output impedance voltage amplifier with near unity gain.
This lecture examines the body effect on the common drain amplifier, showing gm stays unchanged while the output resistance decreases from ro to 1/(gm + gmb), with input resistance unchanged.
Derive a subtractor circuit using n-mos pull-up, applying superposition with a common drain and a common source model to compute Vo, showing contributions cancel to zero output.
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 .
