共源共栅晶体管中的负电阻现象

Cascode topology which includes a high-voltage GaN and a low-voltage Si transistor is an attractive device concept, as it takes advantage of the low on-resistance of GaN while still being compatible with Si gate drivers. It demonstrates the highest threshold voltage among normally-off GaN devices, which is a favorable feature in power electronics. However, the observation of instability in power c...
