Question

The circuit for a single-ended NPN BJT amplifier biased by a PNP BJT current source is shown in Figure 330 where the d.c. output voltage is biased at 5.0V. Pertinent model parameters for each device in this circuit are given in Table 330 below. Assuming that the bulk base resistance is zero for all devices, calculate the collector currents for Q2 and Q3. and the mid-band source voltage gain An of the amplifier. Show all of your work, and explain in detail any and all assumptions you make. Amplifier Biased by a PNP BJT Current Source
