Low-Area Low-Power Delta-Sigma Column and Pixel Sensors
Fall 2011
Delta-sigma analog-to-digital converters (ADCs) are widely used in audio applications, but their use in video applications is emerging. By introducing novel decimator and modulator design flows, this thesis advances the state-of-the-art in delta-sigma data conversion and image sensing. As the...

Spring 2016
A digital pixel sensor (DPS) array is an image sensor where each pixel has an analog-to-digital converter (ADC). Recently, a logarithmic delta-sigma (ΔΣ) DPS array, using first-order ΔΣ ADCs, achieved wide dynamic range and high signal-to-noise-and-distortion ratios at video rates, requirements...
