Explanation: In order to block the dc level a coupling capacitor must be used in series with the input of the voltage follower. 5. To get higher input resistance in AC coupled voltage follower,
A. The output resistance is bootstrapped
B. The input resistance is bootstrapped
C. The bias resistance is bootstrapped
D. The feedback resistance is bootstrapped
Answer:A
Explanation: In order to block the dc level a coupling capacitor must be used in series with the input of the voltage follower. 5. To get higher input resistance in AC coupled voltage follower,
A. The output resistance is bootstrapped B. The input resistance is bootstrapped C. The bias resistance is bootstrapped D. The feedback resistance is bootstrapped
Explanation: Bias resistor connected to ground to provide path in an AC coupled voltage follower, drastically reduces the input resistance of the circuit. Therefore, to get high input resistance, the bias resistance is bootstrapped. 6. Find out AC-coupled voltage follower?
