Question

b and c

R2 a) Select R1 and R2 such that Ic is 1mA (OK for 10% variation – i.e. if Ic is 900µA to 1.1mA, you're OK). You can ignore the effect of Is for this problem. b) Calculate the small signal parameters for Q1. c) Calculate the gain of the amplifier - i.e. gain from input at node X and output at node Y. d) Assume the amplifier is being driven by a source with 200ohm resistance (see schematic below). Calculate the gain from vin to node Y. Include the effects of the R1 and R2 values you calculated in part (a). Assume C, if very large. Refer to Figure 5.55 of your text as an example (but don't forget Rs in your calculations). Vcc = 5V R, Rc1 Kohm Y Rs Q1 200 Ohm R2

3) Common-Emitter Amplifier. Assume B=100, VA=infinity The Is is personalized for you. Add the digits of your student ID number together and multiply it by 10-16 to come up with the Is you should use for this problem. For example, if your student ID number is 010203045, use Is=15x10-16 Amps to solve the problem. For the following circuit: Vcc = 5V R, Rc1 Kohm Q1 IB R2 a) Select R1 and R2 such that Ic is 1mA (OK for 10% variation – i.e. if Iç is 900µA to 1.1mA, you're OK). You can ignore the effect of Is for this problem. b) Calculate the small signal parameters for Q1.
