For the current repeater shown in the circuit, determine IC4 value, Where β = 75.
A. 0.035mA
B. 0.028mA
C. 0.04mA
D. 0.052mA
Answer:A
For the current repeater shown in the circuit, determine IC4 value, Where β = 75.
A. 0.035mA B. 0.028mA C. 0.04mA D. 0.052mA
Explanation: The reference current, Iref = VCC-VBE/R1 =(15v-0.7v)/39kΩ = 0.366mA.
