One of the most important applications of ADCs is in the audio field. Compact Disk (CD) and Digital Audio Tape (DAT) systems are gaining more and more control of the audio market. While the baseband bandwidth in these applications is about 20 kHz, a high resolution on the order of 16-18 bits is required. This high resolution is hard to achieve without external trimming in VLSI technologies. However, $\Sigma\Delta$ ADC's are very promising in this area. While they are tolerant to the primary VLSI technology imperfection, components variations, they use higher sampling rates (compared to the audio Nyquist rate) to obtain the desired resolution. In this class of converters, with a given maximum signal frequency and technology speed, we can achieve higher resolution by applying either higher order loop filters, or multi-bit internal analog/digital and digital/analog converters.

520 $a In this dissertation the system characteristics of a (modified) digitally-corrected multi-bit $\Sigma\Delta$ A/D converter is discussed and the requirements on different circuit elements, obtained by analysis or simulation, will be found and taken into account for the design of each element. A new integrator scheme is also presented. The measured linearity of the internal DAC shows the feasibility of the modified correction scheme. Also the high S/(N+D) ratio (95 dB) obtained by the measurements on the monolithic realization of a second-order 4-bit $\Sigma\Delta$ A/D converter, based on these new features, shows the promising functionalities of this approach.
