摘要
Operation up to 300 degrees C of low-voltage 4H-SiC n-p-n bipolar transistors and digital integrated circuits based on emitter-coupled logic is demonstrated. Stable noise margins of about 1 V are reported for a two-input OR-NOR gate operated on - 15 V supply voltage from 27 degrees C up to 300 degrees C. In the same temperature range, an oscillation frequency of about 2 MHz is also reported for a three-stage ring oscillator.
