A 14.5-Bit ENOB, 10MS/s SAR-ADC With 2nd Order Hybrid Passive-Active Resonator Noise Shaping
IEEE Access, 2022 A new 2nd order noise shaping (NS) based successive approximation register (SAR) ADC is presented in this paper. In comparison to earlier research, this paper considers hybrid passive-active integrators to compensate for the phase error of the passive ...

A Supervised Speech Enhancement Approach with Residual Noise Control for Voice Communication
Applied Sciences, 2020 For voice communication, it is important to extract the speech from its noisy version without introducing unnaturally artificial noise. By studying the subband mean-squared error (MSE) of the speech for unsupervised speech enhancement approaches and ...

On weak lensing shape noise [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 One of the most powerful techniques to study the dark sector of the Universe is weak gravitational lensing. In practice, to infer the reduced shear, weak lensing measures galaxy shapes, which are the consequence of both the intrinsic ellipticity of the sources and of the integrated gravitational lensing effect along the line of sight.

Noise Shaping Enhanced DMT Signal Transmission Utilizing Low-Resolution DAC
IEEE Photonics Journal, 2021 In order to reduce the quantization noise of low-resolution DAC, we study a noise shaping technique that can reshape the white quantization noise to an irregular spectrum, in which the noise in the data subcarrier band is almost transformed into the null

Noise‐shaped filter implementation [PDF]
Electronics Letters, 2018 A system‐level noise mitigation technique is used to design low‐noise single‐ended switched‐capacitor filters which implement noise shaping. The performance is comparable to that of a fully differential structure, while the complexity, power dissipation and chip area are drastically reduced.

Double-sampled cascaded sigma-delta modulator topologies for low oversampling ratios [PDF]
, 2006 This paper presents novel double-sampling cascaded sigma-delta modulator topologies for wideband applications. The proposed modulator structures employ finite impulse response (FIR) noise transfer function (NTF) to achieve the aggressive noise shaping ...

Excess-noise dependence on intracavity aperture shape [PDF]
Applied Optics, 1999 In lasers with nonorthogonal eigenmodes the excess-noise factor K can be large, especially in unstable-cavity lasers with hard-edged intracavity apertures. To the best of our knowledge, we report the first detailed study of the dependence of K on aperture shape.
