A Fully Differential Front End Charge Sampling Amplifier for Medical Ultrasound Imaging in 28nm FD-SOI Technology
(Master thesis, 2015)New generations of ultrasound imaging will contain thousands of receive and transmit elements in a single probe. This leads to challenges in analog front-end circuits concerning low power, low noise, low area consumption ... -
A High Speed Low Cost Capacitor Reset Circuit
(Master thesis, 2011)This master thesis presents the investigation and design of a capacitor reset circuit. The circuit was implemented and simulated using a standard 0.35µm CMOS process. A capacitive load of 20pF should be reset at 0.1% ... -
A Hyperspectral Imaging System using an Acousto-Optic Tunable Filter - Constructing and evaluating the hyperspectral imaging system
(Master thesis, 2015)The aim of this work was to built a high performance hyperspectral imaging system, a state-ofthe- art technology with applications among many fields, like medicine. Chapter 1 introduces this technology and its benefits. ... -
A JPEG2000 Encoder Interpretation
(Master thesis, 2018)Students at the Norwegian University of Science and Technology (NTNU) are developing a CubeSat through the Orbit project. The on-board image compression system will be implemented on an FPGA. Continuing from previous work, ... -
A loadless 6T SRAM cell for sub- & near- threshold operation implementedin 28 nm FD-SOI CMOS technology
(Journal article; Peer reviewed, 2018)Most ultra low power SRAM cells operating in the sub and near threshold region deploy 8 or more transistors per storage cell to ensure stability. In this paper we propose and design a low voltage, differential write, single ... -
A Low Power Parallel RISC-V Processor in 22nm FDSOI Technology for Medical Ultrasound
(Master thesis, 2022)I medisinsk ultralyd blir signalene tradisjonelt filtrert relativt kraftig med analoge filtre i proben før de sendes videre til en ekstern prosesseringsenhet. Ved ̊a i stedet digitalisere signalene og deretter gjøre den ... -
A low‐cost and efficient autonomous row‐following robot for food production in polytunnels
(Journal article; Peer reviewed, 2019)In this paper, we present an automatic motion planner for agricultural robots that allows us to set up a robot to follow rows without having to explicitly enter waypoints. In most cases, when robots are used to cover large ... -
A method for measuring temporal properties of uplink interference in satellite communication
(Master thesis, 2021)Ved kommunikasjon med småsatellitter i UHF-båndet er høyt pakketap et problem grunnet sterk interferens. For å designe et kommunikasjonssystem egnet for satellittkommunikasjon er det derfor nødvendig å ha målinger av ... -
A method for remote sensing of acoustic ship noise
(Master thesis, 2013)Ship noise in the ocean due to commercial shipping has gained increased interest in recent years because of its potential impact on marine life and the ocean environment. Hence, rapid methods to estimate the source level ... -
A Method of Designing Wide Dispersion Waveguides Using Finite Element Analysis
(Master thesis, 2011)High frequency dispersion has a great influence on the perceived performance of a loudspeaker. The directivity of a single transducer primarily depends on driver size, however directivity can be modified using an acoustical ... -
A miniaturized ball-lensed fiber optic NIR transmission spectroscopy-based glucose sensor
(Chapter, 2018)A novel ball-lensed fiber transmission sensor is presented aimed at in vivo continuous glucose monitoring of diabetics. Preliminary results yield 20 mM RMSE, limited by mechanical instability. The design enables flexibility ... -
A Narrowband SDR Transceiver for Amateur Radio Applications: Hardware Design and Construction
(Master thesis, 2013)A VHF radio transceiver targeted for maximum efficiency and flexibility in CubeSat- and UAV applications has been designed, constructed and tested subsystem by subsystem, and ultimately as a complete system. The best case ... -
A Novel Analog Front-End For ECG Acquisition
(Master thesis, 2012)A complete analog front-end for portable ECG systems in 65nm technology was modeled and simulated using Cadence Virtuoso. All the required components for the AFE was incorporated into the continuous-time loop filter of a ... -
