Question

Solve for I1I1 and I2I2 in this circuit with 3 identical transistors if VCC=15VCC=15 VV, R=500R=500 ΩΩ, and β=100β=100.I1=I1= AA
I2=I2= A

(1 point) V cc = By UBC Engineering Solve for I and 1, in this circuit with 3 identical transistors if Vcc = 15 V, R= 500 S2, and B = 100.

Answer 1

Here ,the given circuit is a current repeater circuit with 2 transistor in series with main transistor , the value of currents is calculated step-wise below:  

SOLUTION. We Have. Vee=15V Iste Iil Iu =100 SOO This is current rebeater circuit, and here. current for consecutive trondisters is given by - Jon = Isef of it Here Iref= Vcc- #506-0,0288A Now for transistor 1, N=1, I, = Isap = 0.02388.100 Ij = 0.0 2223A]. for transistor 2 , N=2, Iz = Isab Iz = 0.02996 A B+2: 100+2 T.- Tu 8 = 0.0 38x100 Joo

SOLUTION. We have. Vcc=isu. w. Irof. {sool. Itl Dell =100 This is current current repeater circuit, wound here. for consecutive trandisters is given by - Ien = Iref & AN. Flere I sat = Yec Viorez vote S 0.03 A Now $+2. for transistor 1, N=1, Ij = Irof ß = 0.03X_100 10072 Ij = 0.0 294 Ali transistor 2, N=2, Iz = Isabe n o.08,90+3 Iz = 0.02912 A for
