Question
For a given sample-and-hold circuit, if the value of the hold capacitor is increased, then
Correct answer
(B) droop rate decreases and acquisition time increases
Solution
In a sample-and-hold circuit:
1.The droop rate is defined as . As the hold capacitance increases, the droop rate decreases.
2.The acquisition time is the time required for the capacitor to charge to the input voltage, which is proportional to the time constant . As increases, the acquisition time increases.
