AssumingV_Cesat=0.2V =0.2and beta=50 ,Find the minium base current (I_B) required to drive transitor given in the figure to saturation. |

Answer» Solution :`V_(Cesat)=0.2V and beta=50` `V_(CE)=V_(C C)-I_cR_C` `0.2=3-I_C(1K)` `1110^(3)=2.8 A` `I_C=2.8mA` `I_B=(I_C)/(beta)=(2.8)/(50)xx10^(-3)` `=0.056xx10^(-3)=56xx10^(-6)` `I_B=56 muA`
