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 input-referred 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 Input-Referred 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
