Abstract: Absorbed ionizing particles differentially effect first and second acquiring circuit stages configured to respectively generate first and second acquisition signals. Each acquisition signal has a characteristic that is variable as a function of an amount of absorbed ionizing particles. A measuring circuit generates, on the basis of the first and second acquisition signals, a relative parameter indicative of a relationship between the variable characteristics. A computation of a total ionizing dose is made using a 1st- or 2nd-degree polynomial relationship in the relative parameter.

Abstract: A pulse signal generator has an input receiving an initial pulse signal having an initial period, an oscillator generating an oscillator signal, a first stage and a second stage. The first stage is synchronized with the oscillator signal and configured to deliver a secondary pulse signal having a separation between successive pulses that is representative of an integer part of a division of the initial period by an integer N. The first stage further delivers an auxiliary signal representative of a fractional part of the division and containing, for each pulse of the secondary pulse signal, an indication of a time shift to be applied to the pulse taking into account the separation. The second stage is configured to receive the successive pulses and the corresponding time shift indications and generate successive corresponding pulses of an output pulse signal.
