For a capacitar,
Drap rate decreases as capacitar value is increased
For a capacitar,
Q = cv = i × t
⇒ t ∝ c
∴ Acquisition time increases as capacitar value increased

Answer:
Increasing the value of the hold capacitor in a sample-and-hold circuit has the following effects:
Droop Rate:
- The droop rate of a sample-and-hold circuit refers to the rate at which the voltage across the hold capacitor decreases over time.
- When the hold capacitor is increased, it can store more charge, and therefore, the droop rate decreases.
- This means that the voltage across the hold capacitor will decrease at a slower rate, resulting in less loss of the stored voltage.
- Hence, option 'B' is correct: the droop rate decreases when the value of the hold capacitor is increased.
Acquisition Time:
- The acquisition time of a sample-and-hold circuit refers to the time it takes for the circuit to settle to the desired voltage level after a new sample is acquired.
- When the hold capacitor is increased, it takes more time for the capacitor to charge or discharge to the new voltage level.
- This is because the increased capacitance requires more charge transfer to achieve the desired voltage.
- Therefore, the acquisition time increases when the value of the hold capacitor is increased.
- Hence, option 'B' is correct: the acquisition time increases when the value of the hold capacitor is increased.
Summary:
- Increasing the value of the hold capacitor in a sample-and-hold circuit decreases the droop rate but increases the acquisition time.
- The increased capacitance allows the hold capacitor to store more charge, resulting in a slower decrease of the voltage (lower droop rate).
- However, it also takes more time to charge or discharge the increased capacitance to the desired voltage level, leading to a longer acquisition time.
