ABSTRACT:
Two transferred electron devices are provided in a thermally coupled relationship. One transferred electron device is operated above threshold voltage as an amplifier or oscillator, while the other transferred electron device is operated below threshold voltage so as to supply heat to the first device, to compensate for any operating temperature changes and thereby maintain the first device at a substantially constant temperature.
