Where instead of standalone analog electronic circuits, analog VLSI circuits are more popular where most of the circuits are getting implemented using MOSFET base.
Detailed Explanation
Mixed signal circuits are those that incorporate both analog and digital signals. In today's technology, we often see that in many applications, circuits that previously operated solely on analog signals now integrate digital components for enhanced functionality. This integration allows for more complex processing and improved performance. For instance, while traditional analog circuits handle continuous signals, mixed signal circuits leverage the benefits of digital processing, which allows for versatile control and programmability.
Examples & Analogies
Think of a smartphone as a mixed signal circuit. Its audio system works on analog signals (like sound waves), while its software functions on digital signals (like app interfaces). The smartphone integrates both systems to allow you to listen to music (analog) while also enabling you to change tracks using an app (digital).

Whenever we go down the line and in the present scenario where instead of analog circuit alone in a typical system, electronic system we will see that both digital and analog counterpart, they are mixed together to get something called mixed signal customized design.
Detailed Explanation
The significance of mixed signal design lies in its ability to merge the strengths of both analog and digital technologies. This hybrid approach allows engineers to create systems that are more efficient and responsive to real-world signals. For example, mixed signal circuits can convert analog signals from sensors into digital formats that digital processors can understand, enhancing the system's overall performance. The trend toward mixed signal design reflects the needs of modern applications where various signals must be processed quickly and accurately.
Examples & Analogies
Consider a digital thermostat in your home. It uses analog sensors to measure temperature but employs digital processing to make decisions about heating or cooling. This ability to translate the analog input from the temperature sensor into digital data to control the HVAC system is an example of mixed signal technology in action.
