Abstract
An electronic device includes a cascade of a plurality of transistors. Each transistor of the cascade receives an input voltage at a first terminal of its source/drain channel and receives a sampling clock signal at a control gate. The second terminal of the source/drain path of a first transistor drives a sampling capacitor. The second terminal of the source/drain channel of each subsequent transistor is connected to a backgate of a previous transistor. The backgate of the last transistor is connected to a supply voltage level. The second terminals of the subsequent transistors may be connected to corresponding buffer capacitors. The backgate of the last transistor may be supplied with the input during sampling and the supply voltage level at other times.
