Circuits Designed by Dave Johnson, P.E. :
  • BROAD BAND 2MHz OPTICAL FIBER RECEIVER
    If you need more sensitivity than the above circuit this circuit provides about ten times more gain. It too is designed around an inexpensive plastic optical fiber detector.
  • BROAD BAND 5MHz OPTICAL FIBER RECEIVER
    This circuit is a simple broad band light detector that uses a very inexpensive IC and a PIN photodiode that is packaged for use with plastic optical fibers. It has a bandwidth from 1KHz to over 5MHz. It is great for experimenting with various modulated light sources.
  • CASCODE LIGHT RECEIVER CIRCUIT
    This page provides a detailed explanation of how the modified cascode light receiver circuit operates.  The cascode technique in conjunction with an inductive load provides very high current to voltage conversion as well as very high speed.
  • FET INPUT HIGH SPEED LIGHT DETECTOR
    This circuit is yet another design that converts current from a PIN photo diode to a voltage. It has a bandwidth that extends beyond 50MHz.
