内容記述 | Improved temperature compensation of the output from a GaAs LED can be obtained by connecting the diode in series with the emitter of an n-p-n transistor whose base circuit incorporates a high-gain operational amplifier and a parallel thermistor-resistor network. The temperature dependence of several photodiodes is also reported along with a practical temperature compensation scheme. Finally, the temperature compensation of a photon coupled pair consisting of a GaAs LED and a silicon photodiode is described. The combination provides a stability, linearity, and repeatability of about 1% over the upper 60% of the LED forward current range in the temperature interval from 15 to 45 C. |
