2 cards from this section. Quick, good the night before a test.
What is the minimum required V_BE to turn on a transistor?
Think about the basic operation threshold for BJTs.
What is the role of resistors in determining the output voltage?
Consider Ohm's Law.
What is the minimum base-emitter voltage required for the on state?
Recollect the threshold values we discussed.
True or False: The common mode gain should be higher than the differential gain.
Think about our amplifier’s output requirements.
Given a BJT with a V_BE of 0.6 V and output load impedance, calculate the maximum common mode voltage without distortion. Include all calculations relevant to assumptions.
Use circuit analysis alongside semiconductor equations for transistors.
Design a differential amplifier circuit that achieves a desired output gain while ensuring common mode rejection. Provide analysis for resistor values chosen.
Consider active loads to enhance gain without affecting the common mode significantly.
