AC-DC converters are mostly used as power supplies for microelectronic systems, battery chargers, wind energy applications, electric appliances in household and dc motor drives. Switched-capacitor (SC) network based converters can be good solution to the challenges of 21st century having high voltage conversion ratio and low EMI emissions. The application of this type of converters is in microprocessor...
In scale-space filtering signals are represented at several scales, each conveying different details of the original signal. Every new scale is the result of a smoothing operator on a former scale. In image processing, scale-space filtering is widely used in feature extractors as the Scale-Invariant Feature Transform (SIFT) algorithm. RC networks are posed as valid scale-space generators in focal-plane...
Modified charge-pump based switched-capacitor integrator is a promising technique to reduce opamp power consumption. In this paper, design methodologies are introduced to incorporate such kind of integrator into a low-distortion delta-sigma modulator. A second-order delta-sigma modulator was designed and simulated to verify the proposed modulator topology.
