Global stability, limit cycles and chaotic behaviors of second order interpolative sigma delta modulators [PDF]
, 2011 It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively.

Performance analysis and optimal filter design for sigma-delta modulation via duality with DPCM [PDF]
International Symposium on Information Theory, 2015 Sampling above the Nyquist-rate is at the heart of sigma-delta modulation, where the increase in sampling rate is translated to a reduction in the overall (minimum mean-squared-error) reconstruction distortion. This is attained by using a feedback filter

CMOS sigma-delta thermal modulator [PDF]
2010 IEEE Instrumentation & Measurement Technology Conference Proceedings, 2010 This work presents the design of a 1st-order sigma-delta thermal modulator using a thermoresistive sensor in its feedback loop, as the summing and integrating elements. The proposed system architecture allows the measurement of physical quantities that interact with the sensor, as temperature, thermal radiation and fluid velocity.

W-band radio-over-fiber transmission system with delta-sigma modulation and direct detection
Chinese Optics Letters (COL), 2023 We experimentally built a W-band photonics-aided millimeter-wave radio-over-fiber transmission system and demonstrated the delivery of up to 8192-ary quadrature amplitude modulation (QAM) signal.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Low-Pressure Small MEMS Accelerometer Using Sigma-Delta Modulation
Proceedings, 2018 Encapsulation of MEMS accelerometers in vacuum is advantageous, since it allows integration with other sensors, leading to size and cost reduction. One technique to operate MEMS accelerometers in vacuum is the use of closed-loop Sigma-Delta modulation ...

Molecular Oncology, EarlyView.Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Analysis of Booth Multiplier based Conventional and Short Word Length FIR Filter
Mehran University Research Journal of Engineering and Technology, 2018 The optimized implantation of digital filters has remained one of the challenging tasks, for FPGA (Field- Programmable Gate Array) based system designers, due to the involvement of very complex circuitry for multiplication.
