The figure shown below is a sample and hold circuit used at a sampling rate of 1 kHz with an A / D converter having conversion time of 200 μ sec. The op-amp has an input bias current of 10 nA. The maximum hold error (in mV) is ________.
For a given sample-and-hold circuit, if the value of the hold capacitor is increased, then
A signal channel signal acquisition system with 0-10 V range consist of a sample and hold circuit with worst case drop rate of 100 μV/ms and 10 bit ADC. The maximum conversion time for the ADC is
When a time-varying signal has to be digitized using an ADC, which of the following is necessary to use before digitization?
In A/D converter, what is the time relation between sampling period T and the duration of the sample mode and the hold mode?
