Abstract: Certain aspects provide a method for object detection. The method generally includes: transmitting, via a first antenna, a transmit signal generated via a first transmit chain, the transmit signal being generated based on a mixer output signal; receiving a first receive signal via a first receive chain coupled to a second antenna, the first receive signal being associated with the transmit signal; generating, via a first phase shifter, a first phase-shifted signal based on an adjustment signal received via a signal path coupled to the first transmit chain, the adjustment signal being generated based on the mixer output signal; combining the first phase-shifted signal and the first receive signal to generated a combined receive signal, wherein a phase-shift setting of the first phase shifter is controlled based on at least one of a mutual coupling component or a phase noise of the combined receive signal.

Abstract: An inductor structure has a first terminal and a second terminal, and includes a conductor path between the first terminal and the second terminal. The conductor path includes a first inductor, a second inductor, a third inductor, a fourth inductor, a fifth inductor, and a sixth inductor. The conductor path may be configured such that, when a current flows from the first terminal to the second terminal, the current flows in a first direction in the first inductor, the third inductor, and the fifth inductor, and the current flows in a second direction in the second inductor, the fourth inductor, and the sixth inductor. The first direction may be clockwise and the second direction may be counterclockwise, or vice versa.
