Three times of entering a wrong password to access this site… Earlier in 2012, I wrote an introductory post about EKV model and later extended the related topic a little bit in another post – Stay Simple – SquareLaw Equation … Continue reading
Noise Effect On The Probability of Comparator Decision
In the previous post, it is explained why normal distribution with a standard deviation of is used to characterize the circuit inputreferred noise. In this post, we will calculate the probability of comparator decision (High or Low) with the existence of noise. We … Continue reading

Normal Distribution and InputReferred Noise
Normal distribution is frequently assumed when we do circuit analysis. Why? Because there is a saying that the sum of a large number of random variables converges to the Normal. Under what condition is this true? The central limit theorem deals with … Continue reading
Shall We Go for ALLDigital Solution?
I used to characterize myself as an analoger, enjoying the beauty found from Razavi’s analog CMOS book and Hastings’s layout art book. Then, I became worried of being a pure analoger, because it seems Moore’s law tries to push everything … Continue reading
An Interesting Tutorial Given by Mr. Matching
Are you familiar with this seminal paper, titled “Matching Properties of MOS Transistors” with the first author Marcel Pelgrom? Yes! Pelgrom, the Mr. Matching! I happened to find an online tutorial dealing with component matching given by him from IDESA. … Continue reading

A Paper Talking About Circuit Design Trends
As a circuit designer, it’s good to read, to know, or to think about the trends in his/her domain. It was sooo late that I came to realize it ):. However, I, fortunately, anyway, realized its importance and made up … Continue reading
