CS analog-to-digital converter

An analog-to-digital converter (ADC) is a device that uses sampling to convert a continuous quantity to a discrete-time representation in digital form. The reverse operation is performed by a digital-to-analog converter (DAC). ADC and DAC are the gateways between the analog world and digital domain. Most signal processing tasks are implemented in the digital domain. Therefore, ADC and DAC are the key enablers for the digital signal processing and have significant impacts on the system performances.

In this chapter, we study the literature of CS-based ADCs. We introduce the traditional ADC and its concepts first. Then, we study two major types of CS-ADC architectures, Random Demodulator and Modulated Wideband ...
