In an analog sample-and-hold circuit, acquisition time is the time required after entering sample mode for the held voltage to?

  • ASettle sufficiently close to the input value
  • BDecay completely to zero
  • CReach the supply voltage regardless of input
  • DComplete one oscillation cycle
Report an error
Correct Answer: A. Settle sufficiently close to the input value
Explanation: Acquisition time measures how long the circuit needs to charge its hold capacitor and settle to the new sampled input within a specified error.
Reference: Standard analog electronics: sample-and-hold acquisition time
