Perrott. Massachusetts Institute of Technology. Dept. of Electrical Engineering and Computer Science. Massachusetts Institute of Technology. Dept. of Electrical Engineering and Computer Science. Electrical Engineering and Computer Science. Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2009. In title on title page, "[Delta]" and "[Epsilon]" appear as upper-case Greek letters. Includes bibliographical references (p. 135-140). The use of a VCO-based integrator and quantizer within a continuous-time (CT) [Delta] [Epsilon] analog-to-digital converter (ADC) structure is explored, and a custom prototype in a 0.13 [mu]m CMOS with a measured performance of 81.2/78.1 dB SNR/SNDR over a 20 MHz bandwidth while consuming 87 mW from a 1.5V supply and occupying an active area of 0.45 mm2 demonstrated. A key innovation is the explicit use of the oscillator's output phase to avoid the signal distortion that had severely limited the performance of earlier VCO-based ADC's, which exclusively made use of the output frequency. Furthermore, the proposed architecture includes a scheme for performing fast dynamic element matching (DEM), enabling first-order shaping of unit-element mismatch in all feedback DAC's. by Matthew Jeremiah Park.
