Summary

Quad diode position sensor.


Description

I am trying to build a circuit to read a quad diode position sensor. The inputs are on the left. The first stage amplifies the photo diode signals. The second stage compares the quadrants and the third stage sums the out puts to give an X Y signal.

Based on description in this link http://www2.bioch.ox.ac.uk/~oubsu/ebjknight/q4d.html
