Gain Error Correction for CMOS Image Sensor Using Delta-Sigma Modulation [PDF]
, 2010 A delta-sigma modulation analog-to-digital converter (ADC) has many benefits over the use of a pipeline ADC in a CMOS image sensor. This includes lower power, noise reduction, ease of maximizing the input range, and simpler signal routing for large ...

Should {\Delta}{\Sigma} Modulators Used in AC Motor Drives be Adapted to the Mechanical Load of the Motor? [PDF]
, 2012 We consider the use of {\Delta}{\Sigma} modulators in ac motor drives, focusing on the many additional degrees of freedom that this option offers over Pulse Width Modulation (PWM). Following some recent results, we show that it is possible to fully adapt

Digital mobile fronthaul based on delta-sigma modulation employing a simple self-coherent receiver.
Optics Express, 2022 The coherent digital radio-over-fiber (DRoF) system is a promising candidate for future mobile fronthaul networks (MFNs) due to its high receiver sensitivity and excellent robustness against nonlinearities.

Colored-Gaussian Multiple Descriptions: Spectral and Time-Domain Forms [PDF]
, 2016 It is well known that Shannon's rate-distortion function (RDF) in the colored quadratic Gaussian (QG) case can be parametrized via a single Lagrangian variable (the "water level" in the reverse water filling solution).
