Low-Power Readout IC for a PMUT-based bladder scanner

Fabrication of an ultraviolet absorption spectroscopy probe for protein quantification in bioreactors

Bioreactors are used nowadays to produce proteins with therapeutical effect that can treat a new range of diseases in humans. Unfortunately, measuring protein concentrations directly inside bioreactors in real time is still an unsolved challenge. This is due the large amount of compounds that can be found inside the bioreactors that interfere...

Implementation of in-situ monitoring techniques for power reduction in smart sensors

Nowadays, smart sensors are widely used in a variety of application domains, such as telecommunication, health care, cars, mobile phones, smart cities. Because of limited battery capacity, low-power design is required for smart sensors. Low-voltage operation is a key leverage to reduce power consumption in smart sensors. However, uncertainties...

Low Temperature Fabrication of SiO2 Films Using Liquid Silicon

In this study, a new fabrication method was implemented to convert liquid silicon into silicon dioxide films through non-vacuum and roll-to-roll compatible processes at low temperatures. The electrical characterization of SiO2 films made from liquid silicon was reported for the first time.

Charge Domain Interlacing CMOS Image Sensor Design

This thesis presents a CMOS image sensor which can implement the charge domain interlacing principle. Inspired by the shared amplifier pixel structure and based on a pinned photodiode four transistor (4T) structure, two innovative pixel designs combined with two different readout directions are presented. These novel pixels are designed to fit...

C-V profiling of ultra-shallow junctions using a buried layer with stepped doping

The paper investigates two-sided capacitance-voltage (C-V) technique for application in doping profile characterization of Si ultra shallow p+-n junctions. Stepped doping profile in the n region is designed for the accurate determination of xn0, a crucial parameter for the extraction of the doping profile in the p region. Medici simulations are...
