Exam 5: Transistor Bias Circuits

Base bias is more stable than voltage- divider bias.

Figure 5 (This is similar to Figure 4 but uses a pnp transistor with the same fi.) -Refer to Figure 5. If RB is increased, VCE will

Refer to Figure 6. Assume VC = 0.07 V and VB = 0.7 V. The fault may be that

Voltage- divider bias requires two power supplies.

Collector feedback bias uses a form of negative feedback.

Figure 4 -Refer to Figure 4. The type of bias shown is

Assume a load line is drawn for a transistor amplifier. If VCC is increased, the load line will

Figure 4 -Refer to Figure 4. Assume you were troubleshooting and found that VE is exactly the same as VEE. The trouble could be caused by

IC and IE are nearly the same in a properly biased transistor.

Figure 5 (This is similar to Figure 4 but uses a pnp transistor with the same fi.) -Refer to Figure 5. The expected emitter voltage is

Assume a pnp transistor is used in a voltage- divider biased circuit. If VB = -2.8 V, VE should be
