Towards a read-out for capacitive displacement sensor in an engineered heart tissue device

Engineered Heart Tissues (EHTs) are a valuable approach enabled by Organ-on-Chip (OoC) technology to model human cardiac tissue. These small microfluidic devices allow the culture and development of living cardiac cells in 3D structures, to reproduce tissue dynamics and functionality in-vitro, thus fostering the development of new and more...

Time-Gain-Compensation Amplifier for Ultrasonic Echo Signal Processing

This is a master thesis about the time-gain-compensation amplifier used for ultrasonic signal processing. It is an important part of the real time 3D echo-cardiography system.

Systematic measurement and optimization of a Universal Transducer Interface in resistive-bridge mode

The Universal Transducer Interface (UTI) is a mass-produced interface circuit which can realize the functions of measuring signals of various sensors such as capacitive sensors, resistive-bridge sensors and resistive sensors. For some of the front-ends, an instrumentation amplifier, which is implemented with dynamic-element-matching (DEM) for...

LC Ladder Based Orthonormal Filter for Impulse-Radio UWB Pulse Generation.

In this thesis, a UWB pulse generator is designed to be implemented in IBM 0.13 um technology. The pulse generator has a high spectral efficiency. Using amplitude control, any mismatch, process variation or temperature variation can be compensated for to comply with the UWB FCC mask. The pulse has an approximate duration of 2ns. The current...
