ELEN 325 HOMEWORK #5 ( Due date: Wednesday October 18, 2006) For the following circuits, find the DC collector currents ( I C ) and verify operating regions of all transistors. Assume β = 100. Simulate the circuits using PSPICE and provide circuit schematics with DC bias points (V and I) annotated. Use Q2N3904 and Q2N3906 transistors for simulation.
