Abstract: According to one aspect, an integrated circuit includes: an electronic module configured to generate a voltage at an output, and an electronic control circuit coupled to an output of the electronic module, the electronic control circuit comprising an emissive electronic component. The electronic control circuit is configured to cause the emissive electronic component to emit light radiation as a function of a value of the voltage at the output of the electronic module relative to a value of an operating voltage of the electronic module, and the operating voltage is specific thereto during normal operation of this electronic module. The light radiation emitted by the emissive electronic component is configured to diffuse to an outer face of the integrated circuit.

Abstract: A testing device for electronic dies includes a first support part and a second support part configured to be removably assembled with each other. The first and second support parts together define at least one housing where at least one electronic die can be arranged to be tested. The electronic die has a first surface with contacting elements. The at least one housing includes a first portion. This at least one housing is arranged to enable the at least one electronic die to occupy a first position in the housing where the first surface is spaced apart from the first portion, and is further arrange to enable the at least one electronic die to occupy a second position in the housing where the first surface bears against the first portion.

Abstract: A method for controlling a signal envelope shape of modulation pulses in a driver of a wireless transmitter includes supplying a first voltage to the driver during a non-modulated state, supplying a second voltage configurable by a configurable modulation index value to the driver during a modulated state, switching between the non-modulated state and the modulated state comprising setting the modulation index value to configure the second voltage level at the same level as the first voltage and then switching between supplying the first voltage to the driver and supplying the second voltage to the driver, and filtering to a limited bandwidth the variations of the second voltage resulting from configuring the modulation index value.
