Assuming that the transistor in the circuit below is in its linear operating region, determine I_c for the given value of I_s. In the circuit of Problem 16 above, how does I_c change as R_L changes? What does GBT stand for? In a bipolar junction transistor (BJT), the collector is controlled by the base current. In a field effect transistor, such as a MOSFET, the drain current is controlled by

Solution

17) Since I_c is controlled by I_b for a BJT , the collector current is independent of R_c , hence I_c is constant

19) Since I_D is proportional to V_gs , the drain current is controlled by voltage between gate and source

20) output of voltage regulator is constant
