Abstract: Certain aspects of the present disclosure generally relate to jamming detection for radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first counter configured to count a number of times that a power of a reception signal exceeds a first threshold. The apparatus also includes a second counter configured to count a number of measurements of the power of the reception signal. The apparatus further includes control logic having a first input coupled to an output of the first counter and having a second input coupled to an output of the second counter. The control logic is configured to determine an amount of jamming over a measurement window based on the number of times that the power of the reception signal exceeds the first threshold and on the number of measurements.

Abstract: An integrated circuit (IC) device includes a first resistive strip having an input terminal and an output terminal. The IC device further includes a second resistive strip having a terminal coupled to a voltage. The second resistive strip may be coplanar with the first resistive strip. The IC device further includes a capacitor formed by the first resistive strip and the second resistive strip.
