D'Urbino, M. (author)This work presents an architecture capable of digitizing every channel of an ultrasound transducer array independently and simultaneously. This feature is achieved by exploiting the frequency response of the piezoelectric transducer in order to save area and reduce to a minimum the required building blocks of the ADC. The transducer is used as...master thesis 2017

Angevare, J.A. (author)A highly digital temperature sensor, based on the thermal diffusivity of silicon, for thermal management applications has been reported. Recently, Thermal-Diffusivity based temperature sensors have undergone a radical change from an analog-based readout architecture to a more digital VCO-based one. However the more digital approach led to...master thesis 2015

Van Vroonhoven, C.P.L. (author)This thesis describes the theory, design and implementation of a new class of integrated temperature sensors, based on heat diffusion. In such sensors, temperature is sensed by measuring the time it takes for heat to diffuse through silicon. An on-chip thermal delay can be determined by geometry and the thermal diffusivity of silicon, and since...doctoral thesis 2015

Markenhof, J. (author)Dark current noise in image sensors is highly sensitive to temperature, and a difference in temperature in image sensors can be seen in the image as a non-uniform noise source. Many CMOS image sensors are integrated in mobile devices and lack a physical shutter to generate dark frame subtraction to compensate for dark current noise. In this...master thesis 2015

Kester, D.M. (author), Overdevest, J. (author)In speed skating, the frontal area of the athlete is one of the major factors that influences the aerody- namic drag he/she experiences [1]. The athlete can minimise the frontal area by going lower, and thus bending more his/her knees. O’Sports would like to manufacture the GonioTrainer, a device that will measure the knee of the skater and...bachelor thesis 2015
