Abstract: An integrated circuit (IC) is provided with a plurality of diode based mm-wave peak voltage detectors (PVD)s. During a testing phase, a multi-point low frequency calibration test is performed on one or more of the PVDs to determine and store a set of alternating current (AC) coefficients. During operation of the IC, a current-voltage sweep is performed on a selected one of the PVDs to determine a process and temperature direct current (DC) coefficient. A peak voltage produced by the PVD in response to a high frequency radio frequency (RF) signal is measured to produce a first measured voltage. An approximate power of the RF signal is calculated by adjusting the first measured voltage using the DC coefficient and the AC coefficient.

Abstract: A high-resolution antenna array includes an equivalent antenna array obtained by arrangement of a first and a second physical antenna array. The equivalent antenna array includes a first and a second equivalent antenna group respectively having a plurality of first and second antenna units arranged at equal intervals. The second equivalent antenna group is translated by a unit interval with respect to the first equivalent antenna group, such that each first and second antenna units are staggered and arranged at intervals along a same direction. A processor obtains a target signal reflected by a target object and carries out a calibration on the target signal to obtain a precise phase difference, thereby obtaining an accurate angle of arrival of the target signal. Thus, through the distribution of antennas, the present invention achieves a high angle resolution and prevents angle ambiguity.

Abstract: Various embodiments wirelessly detect micro gestures using multiple antenna of a gesture sensor device. At times, the gesture sensor device transmits multiple outgoing radio frequency (RF) signals, each outgoing RF signal transmitted via a respective antenna of the gesture sensor device. The outgoing RF signals are configured to help capture information that can be used to identify micro-gestures performed by a hand. The gesture sensor device captures incoming RF signals generated by the outgoing RF signals reflecting off of the hand, and then analyzes the incoming RF signals to identify the micro-gesture.
