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
Derive kT/C from Equipartition Theorem
It’s better to know(actually have to know) kT/C if you design ADCs. First, let’s take a look at its inversederivation (for detailed explanation, please go for elsewhere, there are lots of…): Then, comes the dessert of today – Equipartition Theorem … Continue reading
