An inverting op amp circuit has RF = 3 kilohms and RIN = 1 kilohm. What is the gain of this circuit?

For a Fixed bias circuit having Rc-2.2K0, RB-2400, Vcc=12v and current amplification factor is 100 and the current flowing through the base is 20µA, the value if Collector current in saturation is 3mA O OA O 5.4mA O 1mA

VCC R2 RC- RI RL R1 RE VEE Assume: B=100, VA=150, Vcc=12V, VEE=GND, Rr=2K, R1=160K, R2=300K, RE=3K, Rc=2.2K, and R1=100K. Convert the circuit to a common-collector circuit. Draw the new circuit (assume the same values for the input and load resistances). Then compute the terminal voltage gain, and Rin (for the whole circuit), re-computing any parameters that you need to solve.
