1. traditional analog/rf circuit in next generation technology (45/32 nm) and lower power supply.
2. analog/rf circuitry integrate with digital CMOS.
3. digital assisted/calibrated rf/analog.
4. software defined rf, mulitimode rf.
When people say they want to do low voltage/low power research in analog IC, what can they actually do? The only thing is to change to topology right? Is there really that much flexibility in circuit design for so many masters/phd students to do this type of research?
Interesting topics may be flexible circuits either organic or with nanotechnology to implement things like displays, RFID transceivers etc. but probably falls in the field of material science or VLSI processing more than analog IC.
Seems so hard to come up with a decent analog reserach proposal
