INVESTIGATION OF A TEMPERATURE-STABILIZED, PHOTON-COUPLED, ISOLATOR-PREAMPLIFIER CIRCUIT
Abstract
A theoretical and experimental analysis of a temperature-stabilized, photon-coupled, isolator-preamplifier circuit was conducted. Input signals were applied to a gallium arsenide diode which in turn emitted infrared radiation in proportion to the instantaneous forward current. The radiation was guided through a light pipe into a silicon PIN photodiode. The signals which resulted at the photodiode were therefore controlled by, but electrically isolated from, the input. Both the input circuit and the preamplifier were investigated for temperature effects, and circuits were designed to limit these effects.
