Analysis and Design of a 2.5GS/s 6-bit SAR ADC with a 3-bit/cycle Resolving Scheme

The thesis analyzes the design challenges that arise when developing high-speed ADCs and shows, through an extensive architecture study, that the SAR topology can be used with a sampling rate of 2.5GS/s if asynchronous processing and a multi-bit per cycle approach are adopted. The transistor-level implementation and simulation of a 6-bit SAR ADC...

Energy Management System for a Wireless Indoor Climate Sensor

The Electronic Instrumentation Lab at Delft University of Technology desired to have a demonstrator for low-power temperature and humidity sensors they developed, in the form of a wireless sensor node. This thesis presents the design of the energy management system of this node. The primary design goal was to allow the sensor systems to run for...

Micro spectrometer for the measurement of the composition of new gas

As the world is in need of more sustainable energy sources, the use of new gases like hydrogen or bio-gases seems to be a very attractive one. By mixing these new gases with the traditional natural gas, it becomes possible to have a smooth and economically durable transition. The amount of new gases added may be dependent on the availability,...

Light-Emitting Diode Junction-Temperature Sensing using Various Voltage/Current Measurement Techniques

Given the temperature dependence of various aspects of light-emitting diode (LED) performance, LED temperature sensing is becoming increasingly important in solid-state lighting applications. This thesis presents an electrical technique for junction-temperature sensing based on the measurement of the forward voltage and current of an LED at two...
