The Self-Organizing Map (SOM) is an unsupervised neural networktopology that incorporates competitive learning for the classicationof data. In this thesis we investigate the design space of a system incorporating such a topology based on Spiking Neural Networks (SNNs), and apply it to classifying electrocardiogram (ECG) beats. We present novel...

This work introduces an architecture that is capable of reducing the number of cables coming out of an ultrasound receiver ASIC by a substantial factor without dropping the frame-rate. It employs a newly developed technique named compressive sensing to exploit the ultrasound signal redundancies in the spatial domain.
There are 32 receive...

"The use of high-frequency stimulation for conduction block of the pudendal nerve has potentially high benefits for patients suffering from non-neurogenic urinary retention. Special care has to be put in the design of stimulation parameters to ensure safe operation and prevent electrode and tissue damage. While high-frequency conduction block...

Quantum microarchitecture is a key component in bridging the gap between quantum software and quantum hardware of a fully programmable quantum computer. Confronting the control problem of superconducting quantum processors, an experimental microarchitecture (QuMA) has been proposed in previous work. As the size of the target quantum chip...

The European Union has established two directives that require both public and private buildings to become
nearly zero energy by 2020. This has increased public interest in and development of building integrated
photovoltiac (BIPV) systems. One such BIPV solution is the PowerWindow by Physee. Even though the PowerWindow
does not...

Imaging sensors are remarkable devices which are able to capture moments and present them in a form available to us for years to come. With the use of material properties and photon particles, charges can be produced which, in combination with electric circuitry, transform into information understandable to the human eye and eventually the brain...

Electromagnetic Compatibility (EMC) is a growing issue in the automotive industry. Integrated Circuits (IC's) must adhere to strict Electromagnetic Emission (EME) and Electromagnetic Susceptibility (EMS) regulations to ensure safety in the automotive vehicle. The Internal Supply Regulator (ISR) plays a critical role in the EMC performance of an...

This thesis describes the design and measurement of an IC which can digitize both capacitance and temperature. Capacitance sensing functionality is added to an existing Temperature to Digital Converter (TDC) without adding significant die area. Two kinds of baseline capacitance compensation techniques have been investigated and their performance...

A new method of flexible interposer with vertically aligned carbon nanotube (CNT) embedded in polymer is proposed in this thesis. Interposer, working as electrical routing between different sockets or connections, is being used for spreading connections and rerouting in packaging technology nowadays. With the rapidly growing application of...

SiGe bipolar amplifiers are getting more competitive in terms of noise figure to GaAs amplifiers. However, the linearity of these amplifiers is still limited in view of these GaAs implementations. In order to address and overcome these linearity limitations, this thesis report will start demonstrating that the linearity of SiGe bipolar...

This thesis discusses the d es ign and verification of a high-resolution self-timed incremental ?? ADC. The first self-timed incremental ?? ADC was presented by C.Chen et.al at ISSCC 2013 and this work targets to improve the resolution, linearity and energy-efficiency of a self-timed ADC. Unlike conventional ?? ADCs, a self -timed ADC is capable...

DC-DC converters are critical building blocks in energy harvesting systems which are applied to provide the energy for the implantable biomedical devices. They are required to meet very strict specifications and consume as less power as possible. Therefore, their power conversion efficiency and stability of the functionality in the varying...

The technology scaling favors the Digital PLLs, which is reconfigurable. In the traditional fractional-N ADPLL, whether counter-based or divider based, DCO and TDC are the main two power consuming blocks. Modifying the phase detection part based on phase prediction makes the architecture more energy-efficient. The new architecture leads to the...
