Platform development using MATLAB for Analog-To-Digital Converter IC measurement

With the ever-evolving signal processing, digital circuit processing requires the mounting requirements of Analog-to-Digital Converters (ADCs). Often, there is a need for an ADC that is of high speed with a good dynamic range and accuracy for optimum performance. There has been a rising use of Sigma...
