    Abstract: In an embodiment, a radio frequency (RF) receiver circuit includes a main circuit and a wake-up circuit. The main circuit is configured to process RF signals. The wake-up circuit is configured to detect a reception of the RF signals. The wake-up circuit includes an automatic gain control (AGC) loop, and is configured to have a first operating mode where a set point voltage of the loop has a first substantially constant value, and a second operating mode where the set point voltage of the loop has a second value dependent on a power supply voltage of the wake-up circuit.

    Abstract: The present disclosure relates to a method for powering an electronic device. The electronic device includes at least one universal integrated circuit card or at least one secure element; at least one power supply circuit for said card or secure element; and at least one near field communication module. When the near field communication module changes from a standby or inactive state to an active state, the following successive operations are performed: —the components and circuits of said electronic device are started; —programs of the electronic device and said secure card or element are started at the same time.

    Abstract: A package includes an upper level mounted to a lower level. The upper level includes a stack formed by insulating layers and conductive elements and includes a first conductive track of an antenna. A plastic element rests on the stack. A first cavity is defined in the plastic element. A second conductive track of the antenna is located on a wall of the plastic element (for example, in or adjacent to the first cavity). A second cavity is also defined in the plastic element surrounding the first cavity. A third conductive track of the antenna is located on a wall of the plastic element (for example, in the second cavity). A third cavity is delimited between the upper and lower levels and an integrated circuit chip is mounted within the third cavity and electrically connected to the antenna.

    Abstract: A digital signal processor includes K first electronic circuits. The first inputs receive K groups of G successive coefficients of a polynomial. The polynomial are of degree N with N+1 coefficients, where K is a sub-multiple of N+1 greater than or equal to two and G is equal to (N+1)/K. The first electronic circuits are configured to simultaneously implement K respective Homer methods and deliver K output results. A second electronic circuit includes a first input configured to successively receive the output results of the first electronic circuits starting with the output result of the first electronic circuit having processed the highest rank coefficient of the coefficients. A second input is configured to receive a variable X and the second electronic circuit is configured to implement a Homer method and deliver a value of the polynomial for the variable X on the output of the second electronic circuit.
