A Simple Method of Adjusting Trigger Voltage of HBT Device for ESD Protection
The trigger voltage of the HBT device is important for ESD protection. A method of adjusting the trigger voltage of SiGe Heterojunction Bipolar Transistor (HBT) device is proposed in this paper. The simulation and experiment results show that the trigger voltage of HBT can be simply adjusted by varying the emitter junction area.
