Response to the following problem:
Assume the transistor in the circuit in Figure has parameters β = 120 and VA = 100 V.
(a) Design a bias-stable circuit such that VCEQ = 5.20 V.
(b) Determine the small-signal transresistance function Rm = vo/is.
(c) Using the results of part (a), determine the variation in Rm if 100 ≤ β ≤ 150.
