When designers require the BJT to operate as an amplifier the active mode is the one used. The system design requires measurements to be made on several transistors as they operate in the active mode with iE = 1mA indicate the base currents of 15μA and 25μA. The engineer desires to know ic, α, and β for the two devices. Show all work and determine the values for these parameters.

    Problem 1: BJT DC Circuits Analyze the four circuits below, first analytically and then verify using simulations in PSPICE/Multisim. You have to solve each circuit that is, find the status of the BUT (active, saturation or cutoff mode) and then find all the node voltages and all the currents. Whenever you solve manually always make the following assumptions: for npn BIT VE-0.7V (if the BE junction is forward biased) for pap BIT VEB-0.7V (if the BE junction is forward biased)...
