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.
