WebThe most important characteristic of the BJT is the plot of the collector current, IC, versus the collector-emitter voltage, VCE, for various values of the base current, IB as shown on the circuit on the right. IC = φ (VCE, IB) for constant IB. BJT Common Emitter - Output Characteristics; Initially set rheostat Rh1 = 1 Ω and rheostat Rh2 = 1 Ω. WebExperiment 6: The bipolar junction transistor 6-2 whereas the collector-base junction is reverse-biased (in the case of an NPN transistor, the collector would be at the most positive and the emitter at the most negative). The voltage resultant charge carrier flows within the NPN transistor are illustrated in
WebI R = I C S × ( e x p V C B V T − 1) where, I E S is base-emitter saturation currents, I C S is base-collector saturation currents. V T = k × T q. where, k is the Boltzmann’s constant ( k = 1.381 e-23 V.C/ K ), T is the absolute temperature in degrees Kelvin, and. q is the charge of an electron (q = 1.602 e-19 C). WebObjective: A bipolar junction transistor (BJT) can be used in many circuit configurations such as an amplifier, oscillator, filter, rectifier or just used as an on-off switch. If the transistor is biased into the linear region, it will …
WebThe BJT is "cutoff" because IC is essentially zero and all of VCC appears across the transistor collector-emitter terminals. The BJT is "saturated" if IC reaches its maximum value along the load line (IB > 100 μA). Therefore, the transistor can be operated as an OFF switch with IB = 0 μA and as an ON switch with IB = 100 μA. http://vlabs.iitkgp.ac.in/psac/exp3/index.html
WebIn this region, both BJT junctions are forward biased. V CE is small, e.g. 50-100 mV, but quite large collector and base currents (I C & I B) can ow. This region is not used for ampli cation. There is a low resistance between the C and E terminals; the BJT acts like a closed switch. Figure 4 shows an actual circuit of a BJT
