An Ultra-Low Power Temperature to Digital Converter: for Medical Applications in 180 nm CMOS

This thesis describes the design of an ultra-low power temperature to digital converter. It is intended to monitor the excess heat produced during the wireless charging of implantable medical devices such as pacemakers. The TDC is designed to achieve an accuracy of ±0.1 °C (3 sigma) from 27 °C to 47 °C, and ±0.3 °C (3 sigma) from -40 °C to 85 °C...

Design of Frequency locked loop and Receiver front-end for Burst-Chirp UWB Radar Transceiver for Vital Signs and Occupancy Sensing by monitoring the respiration and heartbeat rate

While there are many technologies and electronic systems used to detect the human vital signs by monitoring the heart beat rate & respiration rate, all these systems rely on physical contact with the human body. Furthermore, each measuring system can only be used for a single person thus increasing the cost and complexity of integrated...

Energy Harvesting From A Piezoelectric Source To Power A Wireless System

Batteries are vital sources in many wireless embedded systems applications like the Tire Pressure Management System (TPMS) in the automobile industry. Also, the growth of electric cars will result in an increasing demand for batteries. Although batteries do not directly pollute the environment during their active life, the production phase and...

Wireless Power Transfer for Low Power Medical Sensors

Internet of Things (IoT) encloses the utilization of sensors, actuators and data communication technologies embedded into physical devices enabling them to be tracked, coordinated or controlled over the Internet. Medical IoT refers to the vision where several wearables, sensors and actuators are scattered inside medical facilities and can...
