HCCS Currents and Circuits Paper
Description
For VA = VB = 0V and neglecting all base currents, design the circuit so that each of Q1 and Q2 operates at a dc bias current of 0.4 mA, VC = VD = +10V, VE = 0V, and Q5 operates at a dc bias current of 1.8 mA. Specify the dc bias current at which each of Q3 and Q4 will be operating and give the required values of R1, R2, R3, R4, and R5. If ? = 100, what must the value of each of the two resistances labeled Re be to obtain an input differential resistance of 54 k?? Find the differential voltage gain of the input stage, Q1?Q2. Find the voltage gain of the second stage, Q3?Q4. Find the voltage gain of the output stage, Q5. Find the overall voltage gain, vout/vid, where vout is the ac output voltage at node E, and vid is the differential input between the bases of Q1 and Q2.
