Unformatted text preview: Run the simulation and check the output le for any errors. If there are no errors, plot I CC versus V CC and print out a copy of the plot. Note: If your I CC is negative, use Awaves to plot the absolute value of I CC . I CC appears to be negative because SPICE deFnes I CC to be going out of the BJT. 1 2-+ V BB I CC-+ V CC Figure 2: Circuit to simulate in SPICE I B 1 Q 1 Q 2 I C 2 Figure 3: Darlington confguration 5. The confguration shown below in Figure 3 is known as the Darlington pair. Assume Q 1 has a DC current gain o 1 and Q 2 has a DC current gain o 2 . Derive the overall current gain, tot = I C 2 /I B 1 , as a unction o 1 and 2 . Do not neglect any currents. tot =...
