A circuit, integrated circuit, and radar system implementing a highly coupled inductor design for a multi-core oscillator is provided. An example circuit may include a plurality of inductors, each inductor including: a first inductor portion and a second inductor portion electrically connected in series. In some embodiments, for each inductor, the first inductor portion may be magnetically coupled to a first or second inductor portion of a first coupling inductor of the plurality of inductors, and the second inductor portion may be magnetically coupled to a first or second inductor portion of a second coupling inductor of the plurality of inductors, where the first coupling inductor and the second coupling inductor are different inductors.

Highly coupled inductor design for reducing area and power consumption of a multi-core oscillator

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.

Method of generating self-test signals, corresponding circuit and apparatus

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.
