2 cards from this section. Quick, good the night before a test.
What is the minimum common mode voltage necessary for Q1 and Q2 to operate correctly?
Refer to the transistor's saturation limits.
Explain why a higher collector voltage limits positive signal swing.
Think about the relationship between collector voltage and supply voltage.
What is the minimum common mode voltage required for operation?
Recall the threshold needed for Q1 and Q2.
True or False: High collector voltage allows for larger positive signal swings.
Think about how voltage levels interact.
If the supply voltage of a differential amplifier is set at 15 V, and the base-emitter threshold remains at 0.7 V, determine the maximum collector voltage setting to prevent saturation.
Refer to the saturation voltage of the transistor.
A designer sets the common mode voltage at 1.0 V. Explain the potential risks of this setting in terms of current behavior in transistors.
Analyze how finely tuned settings impact operational regions.
