ELECTRONIC DEVICE WITH REVERSE BIASED HEMT TRANSISTOR

摘要

PROBLEM TO BE SOLVED: To provide an electronic device having behavior similar to that of a reverse biased Zener diode.SOLUTION: An electronic device 100 includes at least: a first HEMT transistor 106; and bias means 102, 103, 104 capable of at least reverse-biasing the first HEMT transistor by applying a positive voltage between a source 108 and a drain 110 of the first HEMT transistor. The first HEMT transistor is on when the voltage between a gate 112 and the drain is higher than a threshold.
