Analogtodigital converters (ADCs) are ubiquitous, critical components of
software radio
and other
signal processing
systems. This paper surveys the stateoftheart of ADCs, including experimental converters and commercially available parts. The distribution of resolution versus sampling rate provides insight into ADC performance limitations. At sampling rates below 2 million samples per second (Gs/s), resolution appears to be limited by thermal noise. At sampling rates ranging from ~2 Ms/s to ~4 giga samples per second (Gs/s), resolution falls off by ~1 bit for every doubling of the sampling rate. This behavior may be attributed to uncertainty in the sampling instant due to aperture jitter. For ADCs operating at multiGs/s rates, the speed of the device technology is also a
limiting factor
due to comparator ambiguity. Many ADC architectures and
integrated circuit
technologies have been proposed and implemented to push back these limits. The trend toward singlechip ADCs brings lower power dissipation. However,
technological progress
as measured by the product of the ADC resolution (bits) times the sampling rate is slow. Average improvement is only ~1.5 bits for any given
sampling frequency
over the last sixeight years
