Your design turned out to be a huge success. Your boss made enough money to support you a tapeout (tapeout means to design and fabricate a real IC). The drawback of this BJT process you use is the foundry did not characterize the I, of the device. Luckily, you have learned (during the lecture) and re-learned (during the review lecture) the BJT common emitter with source degeneration. For the following circuit, assume the transistor 150, VBE = 0.7 V, VA = 100, and Vth = 26 mV. Assume all capacitors are large enough to act as AC shorts. a Calculate the DC values for Vc, VB, VE, IC, IB, and IE. Compute the AC small signal parameters gm, rm, ro. b Calculate the small signal gain Av Vout/Vbase (from the transistor base to the output node), the input resistance Rin (Looking into the input capacitor to the right), the output resistance Rout (Looking back from the output capacitor to the left), and the overall voltage gain G₁ = Vo/Vin (from the voltage source Vin to the output node). Assume that the transistor's ro is infinite (can be neglected). Vin 50 ww = 200K www. 100K: 10 V 2K ww www. 3K 100 AH" Vout I. 20K Figure 6: BJT Common emitter with source degeneration.
