Abstract 

This research is about making devices that can convert real-world analog signals (likesound or light) to computer-world digital signals (ones and zeros) faster and with betterquality. Those devices help create new applications like high-quality video recording anddirect radio frequency conversion. There are many ways to make these devices, and thisresearch looked at a specific architecture called the Discrete-Time Delta-Sigma Modulator.This architecture was limited in how fast it works, but we found a way to improve it using aunique design process and efficient technology. We created two prototypes, one that couldwork twice as fast the current state-of-the-art and another that could work even faster andefficiently. These prototypes covered a region of uncharted specification territories forthis type of analog-to-digital converter. They helped prove that there was no fundamentallimitation for the highest speed achieved by the previous state-of-the-art.
