• Resumen

  • In recent years, the increase in the number of wireless networks has motivated the research in Software Defined Radios (SDRs). SDRs are expected to directly convert Radio-Frequency (RF) signals to the digital domain, facilitating software-based signal processing. In the open literature it has been presented that LC-based Band-Pass Continuous-Time ΣΔ Modulators (BP CT-ΣΔM) can be used for the implementation of RF-to-digital converters. However, most of reported LC-based BP CT-ΣΔMs have used a fixed center or notch frequency, limiting the covered RF signals range.
