I name the blog as THE SIGNAL RHYTHM. Its mostly gonna on subjects/art which interest me and also about the subjects which i would be interested in developing more fascination.
Topics for Sept-Oct 2018:
1. I am gonna write about how to teach electronics and in detail about the art of analog electronics, specifically quoting the experiences which i observed from Professor of Iranian Origin, who grew up in Canada and US. Let's name him Prof. X. I will reveal his name at the right time.
2. I am gonna pick up one startup company every week and describe about it in detail. I would like to analyze them and understand their design/business and sales process
Analog Electronics Lecture1:
1. This is the fundamental course for any electrical engineer. Its an opportunity for you to learn electrical and critical circuit analysis techniques, design considerations, and to develop intuition about complex analog circuits.
2. Simulators help us in simulating the circuits and verifying the performance. But we cannot simulate everything as the
circuits become exponentially complicated. We have to guide the simulator in the right way.
3. I believe everyone is smart enough in my class and are professionals by themselves, to keep up with the homework and classes.
4. Intuition about anything in this world, cannot be learnt in a week or a day. It takes a LOT of effort and practice. One has to participate, read everyday. Practicing intuition is like going to gym. You do it everyday.
5. Analog Electronics is not a kind of course which one can study for one night before the exam. One can just solve problems on the day before exam. But understanding concepts require time and practice.
6. Invention is about creating new things. If you are designing something, you are creating something. by creating, you invent. Invention requires you to know everything. One has to learn every single existing technique and analyze them before designing. Only when you knew everything, you can invent something profound. I would like to give you an analogy. Assume a big cube with balls. The balls are existing ideas and concepts. Assume that the collision of balls in the cube as new inventions. Only when you have more balls in the cube, there are more chances of collisions. It applies the same with every field.
7. One of the important purposes of this course is for you to learn the scientific language. Language is really important and its easy to work with people whose efficiency of language is extremely good. One should be able to describe all the circuits and techniques in words.
8. Discussion about Signals, Ideal Voltage Source and Current Source.
9. Why does batteries get hot when you short them?
10. Discussion about amplifiers.
11. Why unilateral behavior is required in an amplifier?
12. Discussion about all kinds of controlled sources with practical examples.
13. Ways to solve the circuits (Open circuit voltage method, short circuit current method). How Profound these techniques are?
14. CMOS and BJTs can perform analog functions, but then why do all electronics have more CMOS than Bipolar transistors? For example, Why do IPHONE has more CMOS transistors than Bipolar transistors?
15. Discussion about DC operating Point, Intuitive understanding of the MOSFET current plots.
16. Discussion about different type of amplifier configurations with a single transistor.
17. Let me conclude this lecture by showing an awesome picture: The following is the picture of the invention of transistor in 1947 - point contact transistor.
The invention of transistor revolutionized the world. Who thought at that point of time that this simple transistor would revolutionize the world. If some one is interested in seeing the first transistor, you should visit Nokia Bell Labs in MurrayHill, NJ, USA. It is at this place the transistor was invented.
Think about what all changes the transistor brought in this world?
