Abstract:
A method for characterizing a CMOS logic cell of the partially depleted silicon-on-insulator type (PD-SOI) may include modeling the logic cell and determining internal potentials of transistors of the cell in a dynamic equilibrium state based upon a functional simulation of the modeled cell. This may be done using a binary stimulation signal having an initial logic value. The dynamic equilibrium state may be based upon a cancellation, to within a precision error, of the sum of the squares of variations in the quantities of charge in floating substrates of the transistors taken over a period of two successive transitions of the stimulation signal.
Abstract:
A controllable pulse generator generates the pulses of the signal which are respectively contained in successive time windows, and a control device formulates a control signal for the generator including, for each pulse, an indication of its position in the corresponding window. The control device includes a processor to deliver for each time window, at a delivery frequency Fe greater than the pulse repetition frequency, successive groups of N bits together defining a digital cue of position of a pulse inside the window. Also, a converter converts this digital position cue into the control signal temporally spread over the length (T) of the window and including the indication of position at an instant corresponding to the digital position cue. This makes it possible to position the pulse inside its window with a temporal precision equal to 1/N.Fe.

Abstract:
A circuit for splitting poles between a first stage and a second inverting voltage-amplifier stage of an electronic circuit, comprises, in series between the output of the first stage and the output of the second stage, and in that order, a first capacitor, a second capacitor and a resistor. The circuit further comprises a voltage-divider bridge which is connected between a terminal delivering a substantially constant voltage and the output of the first stage. The output of the voltage-divider bridge is linked to the common node between the first capacitor and the second capacitor, in such a way that a first resistor of the voltage-divider bridge is connected in parallel with the first capacitor.
Abstract:
A method is provided for secured transfer of data from a first memory containing the data element to a second memory through a data bus that is connected between the first memory and the second memory. According to the method, a secret N-byte data element is transferred byte-by-byte through the data bus, with each byte transiting at least once on the data bus. Before each transfer of a byte of the secret data element, a current index ranging from 0 to Nnull1 is randomly chosen, with the current index corresponding to a place value of the byte to be transferred. At each transfer of a byte of the secret data element with a place value equal to the current index, a corresponding bit of an N-byte loading indicator is modified as a function of a loading mode, with the loading mode being an integer ranging from 0 to a first constant. The transfer of the secret data element is ended when the loading indicator takes a predetermined value.
Abstract:
A processing system includes a communication system and a processing core configured to generate write requests. A circuit has associated a slave interface circuit configured to manage an address sub-range and selectively forward write requests addressed to a given address. Configuration data specifies whether the given address is protected/unprotected and locked/unlocked. In response to a received write request, address and data are extracted and a determination based on the configuration data is made as to whether the extracted address is protected/unprotected, and locked/unlocked. When the extracted address is unprotected or unlocked, the slave interface forwards the write request. When the extracted address is protected and locked, the slave interface generates an unlock signal in response to a comparison of the extracted address with the extracted data, with the unlock signal being asserted when the extracted data satisfy a predetermined rule with respect to the extracted address.

A cell includes a Z2-FET-type structure that is formed with two front gates extending over an intermediate region between an anode region and a cathode region. The individual front gates of the two front gates are spaced apart by a distance that is shorter than 40% of a width of each individual front gate.
