    摘要: An embodiment voltage converter includes a first transistor connected between a first node of the converter and a second node configured to receive a power supply voltage, a second transistor connected between the first node and a third node configured to receive a reference potential, a first circuit configured to control the first and second transistors, and a comparator including first and second inputs. The first input is configured to receive, during a first phase, a first voltage ramp and, during a second phase, a set point voltage. The second input is configured to receive, during the first phase, the set point voltage and, during the second phase, a second voltage ramp.

    摘要: An artificial neural network includes a unit cell. The unit cell includes a first binary two-dimensional convolution layer configured to receive an input tensor and to generate a first tensor. A first batch normalization layer is configured to receive the first tensor and to generate a second tensor. A concatenation layer is configured to generate a third tensor by concatenating the input tensor and the second tensor. A second binary two-dimensional convolution layer is configured to receive the third tensor and to generate a fourth tensor. A second batch normalization layer is configured to generate an output tensor based on the fourth tensor.

    摘要: A method of authenticating a first electronic circuit includes generating a first signature using the first electronic circuit, the generating of the first signature being based on states of a plurality of electric nodes distributed within the first electronic circuit. A second signature is generated using a second electronic circuit, the generating of the second signature being based on states of a plurality of electric nodes distributed within the second electronic circuit. The first signature is compared to the second signature. The first electronic circuit is authenticated based on the comparison of the first signature to the second signature.

    摘要: An embodiment pulse generator circuit comprises a first electronic switch coupled between first and second nodes, and a second electronic switch coupled between the second node and a reference node. An LC resonant circuit comprising an inductance and a capacitance is coupled between the first and reference nodes along with charge circuitry comprises a further inductance in a current flow line between a supply node and an intermediate node in the LC resonant circuit. Drive circuitry of the electronic switches repeats, during a sequence of switching cycles, charge time intervals, wherein the capacitance in the LC resonant circuit is charged via the charge circuit, and pulse generation time intervals, wherein a pulsed current is provided to the load via the first and second nodes. The charge and pulse generation time intervals are interleaved with oscillation time intervals where the LC resonant circuit oscillates at a resonance frequency.

    摘要: The electronic control unit includes a communication circuit adapted to receive intelligent transport system messages, an authentication circuit designed to authenticate the received messages, a non-volatile memory configured to record the authenticated received messages, and a secure element. The secure element includes a blacklist of automatically excluded senders and is configured to directly reject a received message from a sender on the blacklist without authentication using the authentication circuit. Alternatively, the secure element includes a whitelist of automatically allowed senders and is configured to directly record a received message from a sender on the whitelist in the non-volatile memory without authentication using the authentication circuit.
