Question

In a sample and hold circuit with two buffers, one at input and the other at output, the primary requirement for both buffers is:

• A. Input buffer: high slew rate; output buffer: low bias current
• B. Input buffer: low bias current; output buffer: high slew rate
• C. Both should have low bias currents
• D. Both should have high slew rate

Hint:

High slew rate in both buffers is essential to maintain signal accuracy in sample and hold circuits.

Answer 1

The Correct Option is D

High slew rate ensures that the buffer can track fast-changing signals without delay. In both input and output stages of sample and hold circuits, maintaining the correct value quickly is critical.
