(from – http://analogcircuits.posterous.com/reverse-engineering-the-cascode) Cascode (shown in Fig. 1) is well known and widely used circuit for creating large-impedances in integrated circuits. Cascode circuits also provide another advantage i.e. isolation between input and output ports and thereby reducing the Miller-effect and as a result cascodes have a good frequency performance. And when impedances achieved from cascode [...]
I am sure that everyone has given presentations on a beamer / screen and will have to do so in the future. Most people I have seen presenting use the default slide show view in which the laptop/computer shows the same view as the projector / screen. This is quite unhandy when you want to [...]

Why do we perform small signal analysis, when we are analyzing or designing analog circuits? This is a fundamental question that I think, is not discussed rigorously enough in the classes or text books on analog circuit design. I will attempt to qualitatively address this question here in this blogpost. Fig. 1 a) Small-signal MOSFET [...]

Here is a nice insight from the guys at theRSA.org into what really motivates us. This video really got me thinking about how can you redefine rewards to get the most out your own self and others; a must watch.
Five additions to the Rands In Repose’s classic essay The Nerd Handbook. This is intended for the significant others of nerds and is a good read for anyone trying dive into the mind of nerds.
The recent post by Navin on education got me thinking about one of my favorite topics once more – educational reforms. Specifically, what to do about education in the post-information-revolution world?

Just a random thought… is education really killing jobs or are there huge flaws in the assumptions below? We have an ever increasing population but the increase in population is somewhat linear with increase in jobs More and more people are going to university and getting university degrees This leads to us having to invent [...]
