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

Text Solution

Verified by Experts

`V_Cesat`=0.2V and `beta`=50
`V_CE=V_CC-I_CR_C`
`0.2=3-I_C(1k)`
`10^3I_C=2.8A`
`I_C=2.8mA`
`I_B=(I_C)/(beta)=(2.8)/(50)xx10^(-6)`
`I_B=56muA`
