Monolithic GaAs multivibrator for operation at temperatures up to 300 degrees C

A technology for temperature-stable GaAs integrated circuits is described, using as an example a monolithic multivibrator. The performance of this multivibrator and the different modes of operation are presented. It is shown that conventional models for integrated circuits fail at temperatures higher than 200 degrees C and that only careful design may prevent failures due to electric overstress, which is more probable at high temperatures.
