Problem 2: In the circuit on Figure P2, BJT NPN Q1 and Q2 emulate a Darlington Pair (DP). It should be noted that Q1 and Q2 are such that their current gains are B1 B2 = B = 99. Moreover, capacitors C1 and C2 can be assumed to be very large. Note: The DC analysis of the DP circuit below can be done in a similar fashion as what you do when only dealing with one transistor. Express the current...
