Question

Explain global process variation with respect to mixed signal analog and digital design by giving an example.

Answer 1

A mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die.[1][2][3][4] In real-life applications mixed-signal designs are everywhere, for example, a smart mobile phone. However, it is more accurate to call them mixed-signal systems. Mixed-signal ICs also process both analog and digital signals together. For example, an analog-to-digital converter is a mixed-signal circuit. Mixed-signal circuits or systems are typically cost-effective solutions for building any modern consumer electronics applications.
