Consider the circuit shown in Figure P9.64. (a) The output current of the op-amp is (1.2 mathrm{~mA})

Question:

Consider the circuit shown in Figure P9.64.

(a) The output current of the op-amp is $1.2 \mathrm{~mA}$ and the transistor current gain is $\beta=75$. Determine the resistance $R$.

(b) Repeat part (a) if the current is $0.2 \mathrm{~mA}$ and the transistor current gain is $\beta=100$.

(c) Using the results of part (a), determine the op-amp output current if the input voltage is $6 \mathrm{~V}$.

(d) Using the results of part (b), determine the op-amp output current if the input voltage is $4 \mathrm{~V}$.
