If V1 5 5 V in the circuit of what value does R3 need to be changed to if we want Q2 to operate right at the edge of saturation (EOS)? Hint: as long as a BJT is known to be in the FA region, it is quite acceptable to approximate IC > IE.

If V1 5 5 V in the circuit of fi nd all terminal voltages and currents for the two BJTs. What modes are they operating in?
