Depth sensing technology has developed rapidly recently due to its broad applications. Time-of-Flight (ToF) is a popular technology in depth sensing because of its advantages in high measuring accuracy and low complexity in image processing. ToF technologies are divided into two kinds: indirect time-of-flight (iToF) and direct Time-of-Flight ...

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 photoplethysmogram (PPG) is an important optically-obtained bio-signal that enables convenient daily monitoring of heart rate and oxygen saturation (SpO2). Most state-of-the-art PPG sensing systems require an off-chip photodiode, and the photodiode's output parasitic capacitance limits the power-noise trade offs. The objective of this project...

The current generation of power management integrated circuits require fully integrated, low cost and low power solutions for voltage regulation. As final blocks in the internal power supply chain, excellent performance linear voltage regulators are required, especially in terms of dynamic response and stability. Since many voltage regulators...

This thesis describes the design of a digital backend for a resistor-based temperature sensor realized in a 180nm CMOS process. The sensor’s analog frontend outputs a bitstream at 500kHz, which is then decimated and linearized with the help of 3 different polynomials, whose coefficients are obtained after a calibration process. A polynomial...

Many applications require wide bandwidth transmitters, but unfortunately, they usually have way less than 50% average drain efficiency for their modulated signals. This low efficiency is a significant drawback in all wireless applications, both for battery power devices and base stations. The Doherty radio frequency (RF) power amplifier...

The on-field performance and lifespan of PV modules are affected by the interaction of numerous parameters, among which temperature, strain, and humidity. Among these parameters, only temperature is occasionally measured in PV installations, and such monitoring is often external to the module. This limits its use and does not provide accurate...

Quantum computing offers exponential speed-up for problems that are computationally intractable with classical computing. However, quantum processors with thousands to millions of quantum bits (qubits) are needed. Room-temperature electronics are used to control and readout today's qubits operating at cryogenic temperature. As the number of...
