Unlimited Sampling From Theory to Practice: Fourier-Prony Recovery and Prototype ADC

Following the Unlimited Sampling strategy to alleviate omnipresent dynamic range barrier, we study problem of recovering a bandlimited signal from point-wise modulo samples, aiming connect theoretical guarantees with hardware implementation considerations. Our starting point is class non-idealities that observe in prototyping an unlimited sampling based analog-to-digital converter. To address these non-idealities, provide new Fourier domain recovery algorithm. approach validated both theory and via extensive experiments on our prototype converter, providing first demonstration for data arising real hardware, current previous approaches. Advantages algorithm include it agnostic threshold can handle arbitrary folding times. We expect end-to-end realization studied this paper will pave path exploring methodology number world applications.
