Abstract
  • Demands of today's integrated society dependent on communication systems have driven the creation of ever more efficient analog-to-digital converters. For the same reasons, digital circuitry has rapidly expanded to serve all the different systems and needs of consumers. The trend of technology development has been to make these digital circuits more efficient. This has led to a degradation of key analog parameters which make the ubiquitous operation amplifier less efficient. Ring amplifiers are an emerging circuit meant to replace the operational amplifier. This dissertation details the design and operation of ring amplifiers. It presents two prototype analog-to-digital converters using ring amplifiers. One ring amplifier employs the use of current-starved inverters and a dynamic deadzone to achieve 74 dB signal-to-noise-distortion ratio at 20 MSPS in a 180 nm complementary metal–oxide–semiconductor process. Another ring amplifier using a correlated level shifting scheme to achieve 74 dB signal-to-noise-distortion ratio at 40 MSPS is presented.
