Application Notes

  • Bias Voltage and Current Sense Circuits for Avalanche Photodiodes &mdash AN92
    PDF, 1.1 Mb, File published: Nov 1, 2002
    Avalanche photodiodes, used in laser based fiberoptic systems, require high voltage bias and accurate, wide range current monitoring. Bias voltage varies from 15V-90V and current ranges from 100nA to 1mA, a 10,000:1 dynamic range. This publication presents various 5 volt powered circuits which meet these requirements. Appended sections detail specific circuit techniques and cover measurement practice.
