Non-Inverting Voltage Amplifiers 0.0 / 5 ? EngineeringEDCBTEC NationalEdexcel Created by: NatmacCreated on: 24-03-20 10:34 What will happen if the gain of an op-amp is large? It will result in an exceedingly small input voltage will result in the op-amp saturating. 1 of 10 What happens when we use feedback to reduce the gain of the op-amp takes the output and feeds it back to the input where it is mixed with the original input signal. 2 of 10 when does negative feedback occur? When a sample of the output is fed back to the inverting input. 3 of 10 what are the two signals for the amplifier? The input signal and feedback signal. 4 of 10 What is the purpose of a non-inverting amplifier? To change the input signal without altering the polarity of the signal. 5 of 10 How can a non-inverting amplifier be constructed? Using an op-amp and two resistor values in a potential divider arrangement. 6 of 10 How is the gain of the amplifier governed? The resistor values in the potential divider. 7 of 10 Name an advantage of Negative Feedback The gain of the op-amp has been reduced to a more useful figure 8 of 10 Name another advantage of Negative Feedback Increases the bandwidth of the amplifier 9 of 10 Name another advantage of Negative Feedback a non-inverting amplifer cannot attenuate 10 of 10
