Title :
Process Variation and Pelgrom´s Law [Circuit Intuitions]

Abstract :
The past three articles were related to the small-signal operation of MOS circuits. In this article, we step back and look at dc operation of a simple current mirror and how the process variation can affect the accuracy of the currents produced. We review this through a simplified design of a current-based digital to analog converter (also known as IDAC).
