Step 1 of 4 6.012E Refer to Figure 6.14 in the text book for the transistor circuit. The dc power supply utilized is The common-emitter current gain of the transistors is, The base to emitter voltage of the transistors is, = 0.8 V. This exists at the collector current of ic = mA To obtain a collector voltage Vc of +0.5 V , the voltage drop across the resistor Rc must be equal to Determine the resistance Thus the value of resistance Rc is 500 Ω Step 2 of 4 Determine the base to emitter voltage of the transistor. = In = =0.817 V Since the base is at the emitter voltage is, = Step 3 of 4 The common-base current gain for is, 100 = 101 =0.99 The emitter current is, mA Step 4 of 4 Determine the required value of the emitter resistance. Substitute -0.817 V for and A for 0.683 = 2.02x10⁻³ Thus, the emitter resistance is 338 Ω
