Embodiments of the present disclosure provide apparatuses and systems for proximity communications. The apparatus may include an integrated circuit (IC) package with a central processing unit (CPU) circuit, an input-output (I/O) circuit coupled with the CPU circuit, and a dielectric electromagnetic waveguide coupled with the I/O circuit, to enable communications between the CPU circuit and another apparatus. In another instance, the apparatus may include a plurality of coupler pads disposed on a first surface of the apparatus; and a processor electrically coupled with the coupler pads. One of the coupler pads may form capacitive coupling with one of coupler pads disposed on a second surface of another apparatus, in response to a placement of the first surface in at least partial contact with the second surface, to enable proximity data communication between the processor and the other apparatus. Other embodiments may be described and/or claimed.

Techniques for device-to-device communications

A receiver system includes a blocker detector circuit configured to receive a radio frequency (RF) input signal and detect an existence of a blocker therein, and further configured to output a blocker detection signal indicative of the existence of the blocker. The receiver system further includes a configurable receiver circuit configured to receive the RF input signal and the blocker detection signal, and selectively configure the configurable receiver circuit between a first mode wherein the configurable receiver circuit exhibits first linearity characteristics, and a second mode wherein the configurable receiver circuit exhibits second, different linearity characteristics based on the blocker detection signal.

Real-time blocker-adaptive broadband wireless receiver for low-power operation under co-existence in 5G and beyond

A mixer-first receiver operates to generate filtering and analog-to-digital conversion concurrently and adaptively, while removing an LNA before a mixer to enable integration with digital baseband circuits. A plurality of switching capacitor arrays are integrated with a hybrid analog-to-digital filtering component. Switching capacitor arrays of the plurality of switching capacitor arrays can be selectively modified to perform both the filtering operation and the conversion operation together. The same switch capacitors of a switching capacitor array can be utilized in one phase of a clock cycle for the filtering and in another phase of the clock cycle for the conversion.

Techniques for forming high-bandwidth proximity connection between capacitively coupled plug and receptacle are described herein. A system for achieving capacitive coupling between contactless pads is described. The techniques include aligning and retaining the plug and receptacle in close proximity to one another. The techniques include cancelling crosstalk in the system based on the symmetry and orientation of differential pairs comprising signal pads. The techniques include enabling a high-bandwidth proximity transmission by filtering the transmission using a silicon buffer component.
