Abstract:
A sample-and-hold circuit is provided. The sample-and-hold circuit includes an input one or more dedicated capacitive elements, one or more parasitic capacitive elements connected to said one or more dedicated capacitive elements, an output, a group of switches, and a control unit. The control unit controls said switches so as to interconnect said input, said one or more dedicated capacitive elements, and said output in a cyclic manner in accordance with a sample-and-hold cycle.
