Chen, P. (author)The technology scaling favors the Digital PLLs, which is reconfigurable. In the traditional fractional-N ADPLL, whether counter-based or divider based, DCO and TDC are the main two power consuming blocks. Modifying the phase detection part based on phase prediction makes the architecture more energy-efficient. The new architecture leads to the...master thesis 2014

Pillai, A. (author)Millimeter-wave passive radiometers have earlier been designed in III-V integrated circuit (IC) technologies, due to their higher carrier mobility when compared to silicon, resulting in higher transit frequencies (fT) thereby enabling to operate at higher frequencies. However, increased fT in SiGe BiCMOS technology has generated interest for...master thesis 2014

Wu, J. (author)Wind sensors are widely used in many critical applications, such as navigation, weather forecast, aerospace and wind energy assessment. The thermal wind sensor can measure wind speed and direction at the same time, by measuring the temperature gradient on the sensor’s surface which is induced by the wind flow. Compared to traditional mechanical...master thesis 2013

Elumalai, I. (author)Voltage reference buffers have always been the most power-hungry blocks in switched-capacitor SAR ADCs. High frequency dynamic loading of the buffer by the capacitive DAC causes glitches on the reference voltage, and the buffer has to be fast enough to recover such transients to 1/2 LSB precision in every bit cycle. Such stringent requirements...master thesis 2013
