Bjt as a switch simulation
WebBasic circuit of a PNP transistor as switch. In the fixed bias configuration of the PNP transistor as a switch, in addition to the transistor and the load a base resistor R B is needed. It defines the base current. Figure 3: Basic circuit of the pnp transistor as a switch. The base must have the lower voltage potential than the emitter. 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).

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 http://vlabs.iitkgp.ac.in/be/exp11/index.html
