Delta Sigma Modulators with Beamformers for Application in Medical Ultrasound Imaging

Kaald, Rune (Doctoral theses at NTNU;2017:52, Doctoral thesis, 2017)

Portable medical ultrasound solutions require a high degree of compactness and low power consumption, without sacrificing image quality. In this dissertation we investigate the feasibility of employing a continuous time ...
Modelling, Simulation and Implementation Considerations of High Speed Continuous Time Sigma Delta ADC

Kaald, Rune (Master thesis, 2008)

A found state of the art Continuous Time Sigma Delta ADC is modelled and simulated for the presence of nonidealities. A comparison between two Excess Loop Delay compensation techniques is done, the digital differentiation ...
