Bandpass Sigma–Delta modulation: The path toward RF-to-digital conversion in Software-defined radio

This paper reviews the state of the art on bandpass ΣΔ modulators (BP-ΣΔ Ms) intended to digitize radio frequency (RF) signals. A priori, this is the most direct way to implement software-defined radio (SDR) systems since the analog/digital interface is placed closer to the antenna, thus reducing th...
