Malotaux, E.S. (author)To accommodate the growing demand for wireless communications, new techniques are required to increase throughput of wireless networks. One technology aiming to increase the spectral efficiency of wireless devices is full duplex (FD) radios. These systems are capable of single carrier transmission and reception and could ideally double the...master thesis 2013

Zeng, Z. (author), Pertijs, M.A.P. (author), Karabacak, D.M. (author)This paper presents an energy-efficient readout circuit for resonant sensors that operates based on a transient measurement method. The resonant sensor is driven at a frequency close to its resonance frequency by an excitation source that can be intermittently disconnected, causing the sensor to oscillate at its resonance frequency with...journal article 2013

Dyachenko, V.A. (author)In this work a low power SAR ADC with 8.9 ENOB for wireless communication systems is presented. A capacitive charge redistribution DAC with a unit capacitor of 0.5fF is used. The implemented charge-sharing technique, allows the use of 2^(N-1) + 1 unit capacitors, instead of the conventional 2^N , thus decreasing the DAC area and the DAC...master thesis 2012

Panchanan, G. (author)Bandgap references are used in many ICs to produce ‘stable’ and ‘temperature-independent’ voltage. This thesis describes a sub-1V bandgap reference in 40 nm and 0.16 µm CMOS technologies that is functional from -40 oC to 125 oC. Traditionally, BJT based references are commonly used, but produce an output voltage of 1.2 V and are not suitable for...master thesis 2012
