Questions & Step-by-Step Solutions
In a non-inverting amplifier configuration, what is the relationship between the input and output voltage?
Step 1: Understand that a non-inverting amplifier is a type of amplifier where the input signal is applied to the non-inverting terminal of the operational amplifier.
Step 2: Identify the input voltage as Vin, which is the voltage you apply to the amplifier.
Step 3: Recognize that the output voltage, Vout, is the voltage that comes out of the amplifier after amplification.
Step 4: Learn the formula for the output voltage in a non-inverting amplifier: Vout = Vin * (1 + Rf/Rin).
Step 5: In this formula, Rf is the feedback resistor and Rin is the input resistor. These resistors determine how much the input voltage is amplified.
Step 6: Realize that if Rf is larger than Rin, the output voltage (Vout) will be greater than the input voltage (Vin), meaning the signal is amplified.
