WebA new, physics-based, large-signal SPICE model for graded-base HBT's is reported. The novelty of the model lies in its use of the emitter-base diode ideality factor to account for the voltage dependencies of the tunneling factor and the barrier height for back injection of electrons. This expedient allows the HBT to be simply represented in SPICE by the …

WebThe turn-on of the BJT consists of an initial delay time, td,1, during which the base-emitter junction capacitanc is charged. This delay is followed by the increase of the collector current, quantified by the rise time, trise. Th rise time is obtained by applying the charge contro l equation for the base current, while applying a base curre WebAn apparatus for measuring electrical characteristics of solar panels (photovoltaic modules) wherein the apparatus measures current versus voltage (“I-V”) relationships for both illuminated (“light I-V”) and/or non-illuminated (“dark I-V”) conditions; optionally provides single, dual, or four-quadrant source/sink capability; and measures one or more devices …
