Noise-shapingError-feedback structureData weighted averagingThis paper presents a second-order noise-shaping successive approximation register (NS-SAR) analog-to-digital converter (ADC) employing the error-feedback (EF) structure. With the finite impulse response (FIR) filter based on a single ...
A novel purely VCO-based architecture for a second-order ΔΣ ADC is presented. The proposed architecture achieves in-band second-order quantisation noise shaping. The proposed ADC is highly digital and well suited for design in scaled technologies. The architecture has been validated with MATLAB ...
[lcamtuf] went to great lengths to make the front end as low-noise as possible, including ferrite beads and short leads to prevent picking up RF interference. The digital side has an AVR microcontroller that talks to the ADC and runs an LCD panel, plus switches the 340 nm LEDs on and ...
This article presents a successive approximation register (SAR)-assisted noise-shaping (NS) pipeline architecture which breaks the speed bottleneck of the existing SAR or SAR-assisted-type NS analog-to-digital converters (ADCs). Rather than only for residue amplification and pipeline operation, the ...
Sigma-Delta (Σ-Δ) Analog-to-Digital Converter (ADC) is based on oversampling and noise shaping techniques to achieve high-resolution, and is characterized by low passive component matching requirements and simple structure. In high-resolution audio app
The noise-shaping transfer function will be determined based on the loop filter order used within the design of the modulator. How Does the Processing Gain of an ADC Affect the Noise Density and SNR? There are several applications where the primary signal of interest is located within only a ...
high power and low noise amplifier, RF attenuators, transmitter and receiver system and photonics switches; these all are the crucial instruments for designing a beamforming architecture. A brand new silicon photonics device, named Hydex, has been able to create a delays of 2 nano-second. This ...

Sigma-delta modulators use a noise-shaping technique to curtail the noise power in the band of interest during digital-to-analog conversion. Error feedback modulator employs an efficient noise transfer function for time varying inputs than any other sigma-delta modulators. However, the efficiency of...
