Abstract: A radio-frequency receiver includes built-in-self-test (BIST) circuitry which generates a self-test signal. A local oscillator signal is divided. A self-test oscillation signal is generated, based, at least in part, on the frequency-divided local oscillation signal. The self-test signal is generated based on the self-test oscillation signal. The BIST circuitry includes a divider, which divides the self-test oscillation signal. The frequency-divided local oscillation signal and the divided self-test oscillation signal are used to perform one or more of generating the self-test oscillation signal and controlling the generation of the self-test oscillation signal. The radio-frequency receiver may be an automotive radar receiver.

Abstract: A voltage-controlled oscillator in a phase-locked loop circuit is calibrated via a dichotomous search in a set of candidate frequency bands via a sequence of subsequent halving steps that produce reduced subsets of the set of candidate frequency bands. The reduced subsets have respective upper bound values and lower bound values, as well as central values. The central value of the subset resulting from the halving step of index i in the sequence is a function of the average of the upper bound value and the lower bound value of the subset resulting from the halving step of index i−1 in the sequence.

Abstract: An electronic device has a plurality of integrated circuits fixed to a support between transmitting and receiving antennas. An integrated circuit generates a synchronization signal supplied to the other integrated circuits. Each integrated circuit is formed in a die integrating electronic components and overlaid by a connection region according to the Flip-Chip Ball-Grid-array or embedded Wafer Level BGA. A plurality of solder balls for each integrated circuit is electrically coupled to the electronic components and bonded between the respective integrated circuit and the support. The solder balls are arranged in an array, aligned along a plurality of lines parallel to a direction, wherein the plurality of lines comprises an empty line along which no solder balls are present. A conductive synchronization path is formed on the support and extends along the empty line of at least one integrated circuit, between the solder balls of the latter.

Abstract: Systems and methods for switching on and off a power amplifier including a signal input receiving an input signal and a signal output providing an output signal. The power amplifier includes a control input receiving a gain control signal indicating a requested gain and a control input receiving a mute control signal indicating whether the signal output should be switched on or switched off. A control unit determines whether the signal output of the power amplifier should be switched on and/or off, and if switched on receives data identifying a switch-on ramp and if switched off receives data identifying a switch-off ramp. The control unit generates the mute control signal to switch on the signal output of the power amplifier on or off, and generates the gain control signal as a function of the data identifying the switch-on or switch-off ramp to thereby increase or decrease the gain control signal.

Abstract: An oscillator circuit may include a local oscillator to generate a carrier signal having a tunable frequency, a first modulator and a power amplifier coupled in cascade to the local oscillator to generate an output signal. The first modulator may be activated from a first modulating signal having a first frequency alternatively defining ON and OFF states of the first modulator. An estimator unit may receive the carrier signal during a time window and detect an estimated frequency variation of the carrier signal during the ON and OFF states. A compensation unit may include a second modulator to generate a compensation signal proportional to the estimated frequency variation and modulated with a second modulating frequency. The second modulating frequency may be substantially the same as the first modulating frequency, and the compensation signal may be added to a bias signal of the local oscillator to tune the tunable frequency.
