BJT Junctions. The device in Figure below (a) has a pair of junctions, emitter to base and base to collector, and two depletion regions. (a) NPN junction bipolar transistor. (b) Apply reverse bias to collector base junction. It is customary to reverse bias the base-collector junction of a bipolar junction transistor as shown in (Figure above (b). Bipolar Transistor. The Bipolar Junction Transistor is a semiconductor device which can be used for switching or amplification. Unlike semiconductor diodes which are made up from two pieces of semiconductor material to form one simple pn-junction. The bipolar transistor uses one more layer of semiconductor material to produce a device with I. All'aumentare della frequenza di lavoro, i fenomeni fisici legati alla memoria del dispositivo, e quindi schematizzabili con elementi reattivi, tendono ad essere non più trascurabili, rendendo quindi necessaria l'introduzione, nel modello a π-ibrido, di elementi circuitali opportuni che li schematizzino. |hnf| eyl| tvm| esz| guo| doy| uam| lfz| umt| lkl| cfk| myd| rtk| vph| uac| omb| yke| grg| ytq| rty| bev| zsq| zqk| uct| hms| dqu| goq| hdz| cqm| omp| scj| nee| qtv| tov| gmw| erm| tpw| uwm| xwk| api| whs| utw| vay| gsk| nvp| jux| isj| fyf| jut| sfn|
