Zusammenfassung:An example sample-and-hold circuit includes a first and second input resistors, each having first and second terminals; first and second transistors coupled in series between the second terminals of the first and second input resistors; and third and fourth input resistors, each having first and second terminals; and third and fourth transistors coupled in series between the second terminals of the third and fourth input resistors. A first capacitor is coupled between the first and second transistors and a second capacitor is coupled between the third and fourth transistors. The control terminals of the first and third transistors are coupled together, and the control terminals of the second and fourth transistors are coupled together.
