This thesis describes the implementation of a phase-domain readout system for a thermal-diffusivity (TD) based temperature sensor. Such sensors measure the phase shift of an electro-thermal filter (ETF), which exhibits a near-linear dependency on absolute temperature. The phase shift is measured by a phase-domain delta-sigma modulator (PD-DSM)....

Conventional techniques for audio monitoring, including Passive Audio Monitoring (PAM), often call for the use of environmentally unsustainable and challenging equipment. This among other limitations can disrupt the very environment that is meant to be studied and may also limit the ability to observe an ecosystem in its natural state. <br/><br/...

Olfactory learning in <i>Drosophila </i>larvae exemplifies efficient neural processing in a small-scale network with minimal power consumption. This system enables larvae to anticipate important outcomes based on new and familiar odor stimuli, a process crucial for survival and adaptation. Central to this learning mechanism is the olfactory...

In this thesis, a low-power, high-accuracy BJT-based temperature sensor is proposed, which consists of two main parts: a BJT-based dual-mode front-end (DMFE) and a tracking Delta-Sigma-Modulator (DSM). The front-end employs vertical PNP transistors, which, compared to NPNs, exhibit fewer non-idealities when biased at nA-level currents. The...

To achieve greater specificity in neurostimulation, bidirectional neural interfaces are required to verify the recorded neural response after stimulation. The specific neural interface targeted in this thesis is the epiretinal implant. Due to the heterogeneity of the retinal ganglion cells (RGCs), high-fidelity vision is only possible when all...

An artificial retina can replace some of the functionality of the eye in people that have experienced partial or complete loss of vision. Loss of vision is associated with many negative effects in one’s life and can be a debilitating condition. Artificial retinas in the form of a chip thus offer the potential to greatly improve people’s lives....

Ultrasound (US) neuromodulation is a widely-used technique in the field of neuroscience and medical therapy that uses ultrasound waves to non-invasively modulate neural activity. The miniaturization of modern ultrasonic systems has an intimate relation with system power consumption. As the advancement of Integrated Circuits (ICs) represents a...

Class-D amplifiers have gained popularity for their high-power efficiency, exceeding 90%. Among them, digital-input Class-D amplifiers stand out due to their superior integration and increased immunity to electromagnetic interference (EMI). This project introduces a high-performance digital-input Class-D amplifier, aiming for a dynamic range...

This thesis describes the design of a 3rd order 1-bit delta-sigma modulator whose input-signal range (0 to 1.95V) exceeds its supply voltage (1.2V). By using a passive input stage and a single-OTA resonator, this beyond-the-rails modulator realizes a 3rd order loop filter with only two amplifiers instead of the usual three and thus achieves...

Subgraph matching is a fundamental problem in various fields such as machine learning, computer vision, image processing, and bioinformatics, where detecting specific substructures within an object is often crucial. In these domains, not only structure plays an essential role, but also the feature information on nodes should be incorporated,...

Acoustoelectric imaging is an emerging technology confirmed by in-vivo experiments that can help diagnose and evaluate peripheral nerve neuropathy. The ultrasound transmitter (TX) is required in such systems to selectively focus and apply acoustic pressure on the target volume. Within the ultrasound TX, the power amplifier (PA, commonly called...

Cardiovascular diseases (CVDs) are the top cause of death worldwide, and their diagnosis can be quickly and painlessly achieved through Electrocardiogram (ECG). The diagnosis of electrocardiogram has gradually evolved from manual diagnosis by doctors to one that can be realized using Artificial Intelligence (AI). Early AI still required manual...

Flow sensing is essential in various industrial, commercial, and biomedical applications. Although many types of flow sensors exist, thermal flow sensors are widely used due to their simple sensing elements (heaters and temperature sensors) and low fabrication costs. A low-cost interface for thermal flow sensors can then be realized with a...

Nowadays, to reduce the dependence of devices on cloud servers, machine learning workloads are required to process data on the edge. Furthermore, to improve adaptability to uncontrolled environments, there is a growing need for on-chip learning. Limitations in power and area for edge devices have increased interest in low-cost neural network...

Flat lens antennas are convenient solutions to realize highly directive antennas for millimeter wave and terahertz frequencies. Unlike the traditional three-dimensional bulky lens antennas, flat lenses are compact, low profile, and planar structures that can be manufactured with standard multi-layer technology, e.g. printed circuit board (PCB)...

In ultrasound imaging systems, a charge-sharing successive-approximation-register (SAR) ADC has benefits over a charge-redistribution SAR because the charge-sharing SAR is organically compatible with the subarray beamformer which is deployed to reduce the large channel count. Besides, the noise-shaping (NS) SAR is a promising candidate for...

With the introduction of event-based cameras, such as the dynamic vision sensor (DVS), new opportunities have arisen for low-latency real-time visual data processing. Unlike traditional frame-based cameras that capture entire frames at fixed intervals, each pixel in an event-based camera operates asynchronously, generating an event whenever its...
