Degradation of Junction Parameters of an Electrically Stressed NPN Bipolar Transistor

Toward complementary ionic circuits: the npn ion bipolar junction transistor.

Many biomolecules are charged and may therefore be transported with ionic currents. As a step toward addressable ionic delivery circuits, we report on the development of a npn ion bipolar junction transistor (npn-IBJT) as an active control element of anionic currents in general, and specifically, demonstrate actively modulated delivery of the neurotransmitter glutamic acid. The functional mater...

Validation of an Extended Hydrodynamic Model for a Submicron npn Bipolar Junction Transistor

Degradation of a Light Emitting Silicon Junction of a Bipolar Transistor

The variations of the current-voltage characteristics of a light emitting silicon junction of a bipolar transistor is monitored for the first time along an experiment performed at high constant reverse current. The evolutions of the parameters show the effects of degradation processes which are correlated with induced high injection effects and the changes in the avalanche generated light emiss...

NPN aided fast switching insulated gate bipolar transistor with a p-buffer layer

A novel insulated gate bipolar transistor (IGBT) entitled NPN aided fast switching IGBT (NFS-IGBT) with a P-buffer layer is presented, which enhances the switching speed greatly. Compared with the conventional IGBT, double sided NPN structure is incorporated into the anode to facilitate the turn-off process. The proposed structure is verified by two-dimensional mixed device-circuit simulation, ...

Measurements and comparison of low frequency noise in npn and pnp polysilicon emitter bipolar junction transistors

Low frequency noise characteristics of new high voltage, high performance complementary polysilicon emitter bipolar transistors have been studied. The influence of the base biasing resistance, emitter geometry, and temperature on the noise spectra are discussed. The npn transistors studied exhibited 1/f and shot noise. The pnp transistors, on the other hand, are characterized by significant gen...
