T his article discusses current commercially available analog-to-digital converter (ADC) technology, analyzes its key performance parameters, reviews its historical trends over the past two decades, and postulates future ADC capabilities. Based on an extensive data set including nearly 1,000 commercial products released over the past 20 years, our results show new trends compared to the well-known ADC survey by Walden  . It is also shown that advanced semiconductor technologies and emerging
... ogies and emerging communication applications are strongly influencing the future of ADCs. ADCs play an important role in almost all application fields, which makes it important to review the technology trends every few years. The communications industry has consistently pushed the boundaries of ADCs, and current advances in ultra-wideband (UWB) and software defined radios (SDRs) continue the trend. Today, sensor technologies are becoming increasingly popular and are another area where ADCs play a major part. Here, we analyze ADCs with a general overview suitable for any area of need and present general technology trends apart from technology-specific areas.
