Because the number of research positions is quite limited, I would recommenend that you also consider the following opportunities in a few related areas.
There is an opportunity to work with Prof. Niall Tait, on MEMS and possible applications to RF. Some people believe that Micro Electronic Machines MEMS may revolutionize the design of RF circuits. MEMS show great promise in many areas including filter design which may allow image reject filtering, and switches, which could for example be used for switching between transmit and receive. Beginning work has been done on simple filters and switches, but more work and attempts to include this in an RF circuit still needs to be done. Other applications of MEMS are in optical networks and in the BioMedical area.
Another opportunity is to combine a study of new devices or post-processed material with their incorporation into an analog or RF circuit design. Such work would involve collaboration with one of the faculty members in the devices area. Recent examples have involved the design of post-processed copper over high-K dielectric to build better inductors or transmission lines, used in the design of oscillators and distributed amplifiers. Another example is the use of organic material to design ultra-capacitors for energy storage in ultra low power electronics.
