I and Ian discussed what the transfer functions would look like. Then today, using some old calculations, I put up this notebook which does the calculations for us. The notebook has the calculations typed up in latex too.

This is the first attempt. We have to work on making the EOM path's transfer function closer to the expected model transfer function. And we should use a faster opamp as well, I think.


Edit Fri Oct 4 14:44:33 2019 anchal:

  • Replaced op27 with AD829
  • Added a buffer at the input of PZT to isolate PZT capacitance from the adder circuit.
  • Updated and better circuit schematic coming up by Ian. Removed this image.
