| My Thesis research focuses around implementing a class E amplifier in the RF range. This type of amplifier does not use the transistor in the saturation region relying on the transconductance for gain, but instead uses the transistor as a switch. When you do this at RF, you have issues with the transistor not turning on and off immediately (off being the big issue for this case), and also inductors that need to be used are ideally infinite, but in real life are much smaller than what would be required for operation even closely resembling the ideal case. My fist publication in ISCAS 2004 (Internation Symposium of Circuits and Systems) dealt with these design issues, and almost exactly matched Cadence simulation when the ON and OFF resistance of the transistor were ignored. When I added those resistances, the circuit didn't change much, but enough to give me a possible topic for my next paper! |

As a result, our "state of the art" MEMS research lab is mostly a temporary (I hope) storage facility. I prefer to refer to our lab as the EE -Attic, but I don't think they will be changing the name on the door to that any time soon. |
