READ MORE ABOUT THIS COURSE
This course starts with a look at digital and analog domain in communication, sampling theorem and discrete time analog signal processing.
What you can learn.
- Understand the application and importance of data converters in wireless communication and mixed signal electronics
- Discover the sampling theorem and traversing the digital and analog domain in signal processing and communication
- Identify the basics of DACs and ADCs and characterize them
- Evaluate different families of DACs and ADCs and how to improve their performance
- Evaluate and design different types of data converters for different applications
- Understand the trade-offs between resolution, speed, and accuracy
About this course:
Modern communication requires traversing the digital and analog domain. Every transmitter and receiver has a data converter in the form of an analog to digital converter (ADC) and/or a digital to analog converter (DAC). The course will cover their characterization, classification, design, operation, and how to improve their performance. In the first half of the class, the course will focus on DACs such as current scaling, voltage scaling, charge scaling, subranging and combination of scaling DACs and more. In the second half the course will cover ADCs such as SAR, flash, interpolating, folding, pipelined, delta-sigma and more.
