A control device for controlling a switching converter includes a switch controller that generates a control signal with a switching period for controlling switching of a switch of the switching converter and setting a first interval in which a current flows in the switch, a second interval in which energy is transferred onto a storage element of the switching converter, and a third, wait, interval, at the end of the second interval. The duration of the first interval is determined based on a control voltage indicating the output voltage. A pre-distortion stage receives the control voltage and generates a pre-distorted control voltage as a function of the control voltage and a relationship between one of the first and third time intervals and the switching period, wherein the switch controller is configured to control a duration of the first interval based on the pre-distorted control voltage.

A micro-electro-mechanical device, wherein a platform is formed in a top substrate and is configured to turn through a rotation angle. The platform has a slit and faces a cavity. A plurality of integrated photodetectors is formed in a bottom substrate so as to detect the light through the slit and generate signals correlated to the light through the slit. The area of the slit varies with the rotation angle of the platform and causes diffraction, more or less marked as a function of the angle. The difference between the signals of two photodetectors arranged at different positions with respect to the slit yields the angle.
