Today, everything is digital, yet we remain in an analog world and require an intermediary. Analog to Digital Converters (ADCs) are able to perform this function. They transform analog signal to digital ones that can then be processed using digital circuit components. Because of continuous technological advancements, the ADC speed continues to increase and allows for sampling signals with higher and greater bandwidths.
However , very rapid ADCs don’t have sufficient resolution, they require large silicon areas and are extremely expensive. Additionally, the digital logic could not be able to run at a high speed to execute complicated signal processing operations for signals that are sampled at frequencies close to or above 1 GHz. For RF-related applications, it’s nonetheless more cost-effective and efficient to utilize analog circuitry.
