Abstract: Techniques for increasing the lifespan of a nanopore DNA sensing device are disclosed. A related method may include forming a first electrode, forming a second electrode, disposing the first electrode and second electrode within an insulator, and disposing a lipid bilayer having a nanopore between the first electrode and second electrode. The forming of the second electrode may comprise forming a silver (Ag) layer, pressing a mold into the Ag layer to form a pattern in the Ag layer, removing the mold from the Ag layer, and exposing the Ag layer to an electrolyte.

Abstract: In conventional packaging strategies for mm wave applications, the size of the package is dictated by the antenna size, which is often much larger than the RFIC (radio frequency integrated circuit). Also, the operations are often limited to a single frequency which limits their utility. In addition, multiple addition build-up layers are required to provide the necessary separation between the antennas and ground layers. To address these issues, it is proposed to provide a device that includes an antenna package, an RFIC package, and an interconnect assembly between the antenna and the RFIC packages. The interconnect assembly may comprise a plurality of interconnects with high aspect ratios and configured to connect one or more antennas of the antenna package with an RFIC of the RFIC package. An air gap may be formed in between the antenna package and the RFIC package for performance improvement.

Abstract: An ionic current sensor array includes a master bias generator and a plurality of sensing cells. The master bias generator is configured to generate a bias voltage. Each sensing cell includes an ionic current sensor, an integrating capacitor, a sense transistor coupled between the integrating capacitor and the ionic current sensor, and an amplifier coupled to provide a reference voltage to bias the ionic current sensor. The amplifier includes a first transistor and a second transistor. The first transistor is coupled to receive the bias voltage, and the second transistor is coupled to the first transistor to provide the reference voltage to the ionic current sensor. The second transistor is also coupled between a source of the sense transistor and the gate of the sense transistor.

Abstract: Certain aspects of the present disclosure provide systems and methods for performing a power amplifier characterization. One example method generally includes determining, by a user equipment, if a condition associated with a power amplifier characterization is met. In certain aspects, the method includes determining, by the user equipment, a calibration gap after the condition is met. The method also includes performing, by the user equipment, the power amplifier characterization of the one or more power amplifiers of the user equipment during the calibration gap.
