This work presents a low-noise amplifier (LNA) for ultrasound imaging with built-in continuous time-gain compensation (TGC), which compensates for the time-dependent attenuation of the received echo signal and thus significantly reduces its dynamic range (DR). The proposed design combines the LNA and TGC functions in a single variable-gain...

Hydrogenated Indium Oxide (IOH) has been recognized as a high performance transparent conductive oxide (TCO) due to its excellent mobility (>100 cm2/Vs) and high transparency (>90%) in the visible and near infrared region of the spectrum. Plasma enhanced spatial atomic layer deposition (PESALD), a new type of deposition process developed...

On-chip spectrometers, such as DESHIMA and SuperSpec, require transmission lines with very low loss of tanδ &lt; 10<sup>-4</sup> to achieve sufficient system efficiency. Transmission lines with higher loss would introduce too much signal attenuation in the line from antenna to filter and in the filters themselves. Data regarding the losses of...

In the past few decades, there has been a growing demand for low-cost disposable sensors to be utilized in hazardous and toxic environments such as high temperature and chemically aggressive environments, which can lead to irreversible damage to the sensor. Moreover, by cost reduction, they become more attractive for utilization in developing...

Neural interface in the form of microelectrodes is used to monitor and treat spinal cord injury and other neurological disorders by the means of recording and stimulation. Despite the apparent result of these electrical interventions, understanding of the mechanism behind neural stimulation is still inadequate. The use of optical monitoring...

In this thesis,two essential parts of microspectrometer are designed, fabricated and measured. They are a hot wire of polysilicon with constant temperature profile that used as the IR light source, and the LVOF which is aimed at IR spectral range. In order to have the desired IR source, the hot wire should have temperature distribution as...

From the earliest days, the phenomenon of levitation has always aroused the curiosity of humankind due to its mysterious and unique nature. Levitation systems are particularly interesting because of their non-contact characteristic which provides the possibility to isolate the levitated object from environmental effects like mechanical friction...

In this research a feasibility study was performed on introducing Zener diodes, junction field-effect transistors (JFETs) and double-diffused MOS transistors (DMOSTs) in an existing silicon 0.25 μm BiCMOS process. As a restriction, no changes to the process were allowed. Lateral polysilicon Zener diodes were designed and optimized for low...
