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

Rajendran, L. (author)This thesis presents an incremental ?? capacitance-to-digital converter (CDC) that serves as an interface circuit for a MEMS-based pressure sensor. The thesis presents a systematic analysis of the CDC and compares different CDC architectures. A novel non-linear CDC is also proposed and analysed. Energy-efficiency of the CDC is improved by...master thesis 2013

Den Haas, W. (author), Polushkin, M. (author), Vlasman, I. (author)Om een pH-sensor[1], ontwikkeld binnen het PASTEUR-project [2], aan te kunnen sturen en uit te kunnen lezen is een ontwerp voor een sensorsysteem gemaakt dat de pH en temperatuur in vlees kan monitoren. Belangrijke eigenschappen hiervan zijn het lage energieverbruik, de draadloze digitale communicatie en het kleine formaat. Het systeem meet...bachelor thesis 2013

Guo, F. (author)An interface circuit for a fully-integrated capacitive humidity-sensor is implemented using 0.16?m standard CMOS technology. This interface circuit is intended to be used in a smart RFID sensor platform. This thesis focuses on improving the energy-efficiency of the interface circuit. A third-order incremental delta-sigma converter based on...master thesis 2011

Sakunia, S. (author)This thesis describes the implementation of a Precision Instrumentation Amplifier using a Current Feedback Instrumentation Amplifier topology (CFIA). CFIAs are attractive for sensor readout, because of their high CMRR and their ability to interface with ground-referenced sensors. Several chopping and auto-zeroing techniques have been developed...master thesis 2010
