摘要： A system includes analog supply circuitry providing first and second analog potentials. A switch module assumes first or second states to enable and inhibit transfer of an analog electrical signal from a source module to a user module based upon a driving electrical signal. A driving device drives, based upon the driving electrical signal, a control terminal of the switch module, allowing the switch module to assume the first or second state. The driving device allows the switch module to make a first driving transition from the first state to the second state, and a second driving transition from the second state to the first state. The driving device alternately connects the control terminal to a first reference potential, during the first state, and to a second reference potential, during the second state. The driving device connects the control terminal of the switch module to a third reference potential electrically distinct from the first and the second analog potentials, during each of the time intervals associated to the first or second driving transitions of the switch module.
