         Robert Filkins
        General Electric


Group Members: Elizabeth Mathew, Omar
               Zurita,
Action Items from previous week:
 Continue assembly and analysis of prototype board -
  Began layout of photoreceiver design
 Solve DC/DC converter problems; possibly contact
  vendor -Solved
 Incorporate photodiode into prototype board – Still
  looking for an accurate way to test photodiode
 Update simulations as design efforts change. –
  Switched from using voltage input to current input
  source; varied capacitor and resistor values to
  improve frequency response.

Design Improvements

 Tested the design with different capacitor
  resistor values.
 Will setup a conference call to discuss results
  with our sponsor.
 Testing of second stages in progress (Will
  show results next week).
