| Duh, just realized I'm expected to have a moving part, I found an interesting paper that tested a mic designed so that the membrane acts as the gate to a transistor. If I can design concept with a similar transistor mic integrated with the 3-transistor preamp above I think that will be enough mechanical motion and transistors to be accepted by my professor.
Thanks for the links Bongo. Everyone's designs will be on one wafer so I wont be able to do a real world test, however, the thought of building a micro-scale condenser mic with a dedicated preamp voiced for bass that could all fit under one string should keep the class exciting. |
