Questions & Step-by-Step Solutions
In a differential amplifier configuration, what does the output voltage depend on?
Step 1: Understand that a differential amplifier has two input voltages, which we can call V1 and V2.
Step 2: Recognize that the differential amplifier compares these two input voltages.
Step 3: Realize that the output voltage (Vout) is calculated based on the difference between V1 and V2.
Step 4: The formula for the output voltage is Vout = A * (V1 - V2), where A is the gain of the amplifier.
Step 5: Conclude that if V1 and V2 are equal, the output voltage will be zero, and if they are different, the output voltage will reflect that difference.
