Exam 17: Negative Feedback

The effects of negative feedback does not include

Negative feedback reduces harmonic distortion.

What stabilizes the voltage gain and has an enhancing effect on quantities such as gain stability,distortion,offsets,input impedance and output impedance?

With a voltage-controlled current source,an input current controls an output current.

The closed-loop output impedance is the overall output impedance looking back into the voltage-controlled voltage source amplifier.

What is the term that is used to describe how much the output voltage is attenuated before the feedback signal reaches the inverting input?

Negative feedback can stabilize voltage gain,increase input impedance,and decrease output impedance.

Coupling capacitors can be added to a voltage-controlled voltage source prototype in order to get

Loop gain is the op amp's voltage gain of the forward and feedback paths.
