Abstract
Method for controlling an analogue switch including a transistor to which a variable analogue input voltage Vin is applied on a first terminal between a source terminal and a drain terminal of the transistor while a second terminal between the drain and the source terminal is at a variable output voltage VST, including the steps of: during a first phase, applying a first voltage to the transistor gate, the first voltage equal to a sum of or a difference between Vin and a first constant potential V1, and configured to make the transistor conduct; and during a second phase, applying a second voltage to the transistor gate, the second voltage equal to a sum of or a difference between VST, Vin and a second constant potential V2, and configured to block the transistor, the difference between the first voltage and the second voltage being constant.
