A. Op-amp with low bias current B. Op-amp with higher slew rate C. Buffer or voltage follower D. All of the mentioned
Explanation: When the op-amp is driven by a high input source resistance, the output and input voltage will not be equal due to error at the input. A remedy to this problem is an op-amp with low input bias current and high slew rate should be chosen as a voltage follower. 4. What must be done to block the ac input voltage riding on a dc level?
