Abstract
The invention relates to a low leakage switch having an input node for receiving an input voltage and an output node for providing an output voltage. The low leakage switch comprises a main sampling transistor the backgate voltage of which is biased through other transistors, and wherein the control gate of the main sampling transistor is controlled through a second control signal and the control gates of the other transistors are controlled through a first control signal, wherein the electronic device is further configured to activate the other transistor for adjusting the backgate voltage of the main sampling transistor through the first control signal before activating the main sampling transistor for sampling the input voltage on a main sampling capacitor through the second control signal.
