2. A two-stage amplifier is shown below. Assume Q4 = Q5 = Q6 and all transistors are forward active. TO SIMPLIFY THE CALCULATIONS FOR THIS PROBLEM, IGNORE ro of the NPN transistore, [use r,, = rOn =roa = Infinity]. a a) Find the small-signal input resistance Rin = 20 k A . @ b) Find the small-signal voltage gain vdvin = g afg3 @ c) Find the positive limit of the outputvoltage swing: V,(max) -
3. A current source is shown below. Write an equation that car1 be solved for the output current value I. in the model. Don't assume that VeE = 0.7V for this problem. All transistors are identical. Assume
