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.

What is an active load circuit for amplifier? What is a driver circuit? What makes this unbalanced?

Please solve with steps, using to study. Will upvote!

B. Make a sketch of the channel region when VGS=VGS-OFF and make a sketch of the channel region when ID=IDSS and explain why each channel has this shape. C. Assuming that the measured values for the PF5102 were VGS-OFF= -1V and IDSs 10mA, design a common source amplifier for ID=4mA and VDS= 4V using a 12V supply and combination biasing without degeneration as you did in the laboratory. D. Find the input resistance, output resistance, and voltage amplification of your design using the hybrid-pi model and explain how you measured these parameters in the laboratory.

some one solved it but, I think there is a mistake. can you please just solve number 4 and 5

Derive the output resistance using small signal model for the following circuits, assuming the transistor has output resistance of a transistor is ro and transconductance of gm. Rout PPA Rout Vb- Vbo Rout Rout Vdd Vb- Rout

What are resistors for?  What are capacitors for?   What are transistors for? What are Operational amplifiers for?  What are oscilloscope for?

How did they get case 1 and case 2 and simplify break down for a dummy?
