WebOct 11, 2024 · The *reverse saturation current*, "Is", is the reverse current of the base-emitter junction. This is denoted as "Is" in a diode, a 2 terminal device. But a bjt has 3 terminals, & 2 p-n junctions. The collector base jcn is reverse biased when bjt is biased in its active region. Without base current, the emitter current is the collector base jcn ... WebDec 8, 2016 · The magnitude of this leakage current is small – on the order of picoamps (pA). Since the inputs of bipolar junction transistor (BJT) amplifiers require base currents for proper bias, however, the BJT input bias current is a lot larger – on the order of microamps (µA). Hence, input bias current is an important issue for BJT amplifiers.
WebFig. 7-2 explains the subthreshold current. At V gs below V t, the inversion electron concentration (n s) is small but nonetheless can allow a small leakage current to flow between the source and the drain. In Fig. 7-2(a), a large V gs would pull the E c at the surface closer to E f, causing n s and I ds to rise. From the equivalent circuit in ...
