Bandpass Sigma–Delta Modulation: The Path toward RF-to-Digital Conversion in Software-Defined Radio

Jose M. de la Rosa

Chips2023, 2(1), 44-69;https://doi.org/10.3390/chips2010004

2 March 2023

This paper reviews the state of the art on bandpass ΣΔ modulators (BP-ΣΔMs) intended to digitize radio frequency (RF) signals. A priori, this is the most direct way to implement software-defined radio (SDR) systems since the a...

Methodology for a Low-Power and Low-Circuit-Area 15-Bit SAR ADC Using Split-Capacitor Mismatch Compensation and a Dynamic Element Matching Algorithm

William Bontems and
Daniel Dzahini

Chips2023, 2(1), 31-43;https://doi.org/10.3390/chips2010003

27 February 2023

This paper presents a design methodology for a low-power, low-chip-area, and high-resolution successive approximations register (SAR) analog-to-digital converter (ADC). The proposed method includes a segmented capacitive DAC (C-DAC) to reduce the pow...
