6.
All practical op-amps have input bias currents and voltages that produce output error voltages.
7.
When the open-loop gain of an op-amp is reduced by negative feedback, the bandwidth is increased.
8.
Open-loop gain of an op-amp is the voltage gain without feedback.
9.
Open-loop gain is always smaller than closed-loop gain.
10.
The common-mode rejection ratio (CMRR) is a measure of an op-amp's ability to reject common-mode input signals.
