Planar lenses based on metasurfaces or resonant elements are typically narrowband due to phase wrapping, which is strongly frequency-dependent. On the contrary, true-time-delay (TTD) planar lenses, which do not resort to phase wrapping, can achieve large bandwidths. One convenient way to design wideband TTD lenses is by means of artificial...

A key issue in current quantum computing interfaces is the dense interconnect between electronics at cryogenic temperature (CT) and room temperature (RT). Recently, progress has been made to move more control electronics from RT to CT, reducing interconnect overhead. The next step towards minimal interconnect is a direct wireline interface...

This thesis is concerned with a first time demonstration of a high frequency scanning lens phased­-array with dynamic steering. Such phased­-array could provide the high gain, wide bandwidth, and steering capability that the next generation of wireless ap­plications requires. The phased-­array development was divided into three distinct parts....

In recent years, quantum computers have become increasingly popular, with high-profile companies in-vesting more and more resources into the development of quantum-computing prototypes. Such interest is motivated by the exponential increase in the computing power that quantum computers offer over classical computers, which may be used in several...

IoT refers to a network of connected devices that exchange data for different applications using different wireless standards such as Cellular, ZigBee, Bluetooth, Mesh Networks, and the widely used WiFi. For IoT applications that do not require high data rates but require long-range data transmission and low power operation, a sub 1GHz WiFi...

Neonates are among the most fragile in the human population. Even more so when born prematurely. Their loss of development time in the womb disrupts their growth, and the neonatal intensive care unit environment can add multiple stresses that hinder their development. This can partly be attributed to the intrusive environment of a neonatal...

This work focuses on the improvement of a capacitance-to-digital converter (CDC) based on iterative discharging. Time-domain interpolation is applied on the CDC. With such technology, a high-resolution CDC can be achieved while its fully digital feature can be kept. The proposed CDC achieves a resolution of 2.8fF and a FoM of 1.32pJ/step at 5...

The information of electrical properties of biological tissues within human body can be useful information for diagnosis, tissue characterization, hyperthermia treatment planning and MR safety control.<br/>CSI-EPT is an MR base imaging modality, which reconstructs the electrical properties of the sample. However, this method have not been...

This work presents an ASIC designed to be integrated on the tip of an intra-vascular ultrasound catheter, capable of interfacing 64 ultrasonic transducer elements to an imaging system using only one micro-coaxial cable.<br/>A prototype chip has been taped out that can be used to transmit acoustic waves using a small-area transmit switch. The...
