WebNov 15, 2024 · The BJT is in forward active mode because the supply voltage connected to the collector through R C is much higher than V IN, and this ensures that the base-to-collector (BC) junction is reverse-biased. It’s true that some voltage is dropped across the resistor R C, and consequently, the voltage at the collector is lower than 5 V, but we’ll ... 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 ...
WebJan 11, 2024 · And I found that the reverse leakage current is pretty small – around 3 nano amperes (nA) only. Both temperature and voltage affect the diode’s reverse current, so I used a steady 5VDC power source while taking the DVM readings. ... Temperature Sensor BJT.

I tested with three different transistor types that I happen to have in stock. (These transistors are a little old). The circuit was setup in a solderless breadboard. WebIn CE connection, the leakage current of a transistor is about A. 10 x 10-9 A B. 5 x 10-6 A C. 200 x 10-6 A D. 5 x 10-3 A Answer: Option C; The early effect in a BJT is caused by A. fast turn on B. fast turn off C. large collector base reverse bias D. large emitter base forward bias Answer: Option C
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 ...
