CMOS Power Amplifiers for Wireless Communication Systems

This PhD project is a joint activity with Texas Instruments. The overall goal of the PhD project is to develop a switched CMOS power amplifier (PA) and possibly modulator for varying envelope modulation types of wireless communication. Emphasis is on achieving decent power efficiency while at the same time having e.g. robustness towards changes in load impedance. Linearization techniques must likely be included - for example to predistort the signal before being passed to the input of the PA. Also coupling issues between the PA module and other CMOS circuits should be studied.
