ECL-based SiC logic circuits for extreme temperatures

摘要

Integrated digital circuits, fabricated in a bipolar SiC technology, have been successfully tested up to 600 ℃. Operated with -15 V supply voltage from 27 up to 600 ℃ OR-NOR gates exhibit stable noise margins of about 1 or 1.5 V depending on the gate design, and increasing delay-power consumption product in the range 100 - 200 nJ. In the same temperature range an oscillation frequency of about 1 MHz is also reported for an 11-stage ring oscillator.
