ABSTRACT:
An integrated device for a switching system is disclosed. The device includes control circuitry for generating at least one switching control signal, reference circuitry for generating at least one reference quantity, a using circuit for using the reference quantity, a circuit for storing the reference quantity, and a switch which, in a first operative condition, connects the reference circuit to the using circuit and to the storage circuit in order to apply the reference quantity thereto. In a second operative condition, the switch disconnects the reference circuit from the using circuit and connects the storage circuit to the using circuit in order to apply the stored reference quantity thereto. Finally, the device includes filtering circuitry for keeping the switch in the second operative condition for a filtering period in accordance with the switching of the control signal.
