GSR Amplifier + ADC Circuit

by Carson Reynolds

The GSR amplifer design I posted a previously has been updated by the addition of a PIC microcontroller. As part of my end-of-term duties, I wrote up a report detailing the GSR design. The circuit diagram is tuned to be used with the BlueCore 2 single chip Bluetooth implementation. From this circuit design I will be working to make a CAD drawing of the printed circuit board. I will attempt to fabricate and stuff this board with components next week. Shortly thereafter, this board will be hooked up to the BlueCore 2 and we should have a wireless physiology sensor.
