    Abstract: Systems, devices, and methods related to dual wideband antennas with arbitrary frequency ranges are provided. An example antenna structure includes a high-band patch antenna to wirelessly communicate a first signal in a first frequency band; a low-band patch antenna to wirelessly communicate a second signal in a second frequency band lower than the first frequency band, wherein the low-band patch antenna is stacked vertically below the high-band patch antenna and spaced apart from the high-band patch antenna by a dielectric substrate; a high-band excitation via electrically coupled to the high-band patch antenna; and a low-band excitation via electrically coupled to the low-band patch antenna, wherein the high-band excitation via is separate from the low-band excitation via.

    Abstract: A system current sensor module can accurately sense or measure system current flowing through a sense current resistor by shunting current through a gain-setting resistor and using an amplifier to measure a resulting voltage, with an output transistor controlled by the amplifier controlling current through the gain setting resistor in a manner that tends to keep the amplifier inputs at the same voltage. The resistors can be thermally coupled to maintain similar temperatures when a system current is flowing. The thermal coupling can include conducting heat from a first resistor layer carrying the current sense resistor to a thermal cage layer located beyond a second resistor layer carrying the gain-setting resistor. This preserves accuracy, including during aging.

    Abstract: High speed, high dynamic range SAR ADC method and architecture. The SAR DAC comparison method can make fewer comparisons with less charge/fewer capacitors. The architecture makes use of a modified top plate switching (TPS) DAC technique and therefore achieves very high-speed operation. The present disclosure proffers a unique SAR ADC method of input and reference capacitor DAC switching. This benefits in higher dynamic range, no external decoupling capacitory requirement, wide common mode range and overall faster operation due to the absence of mini-ADC.

    Abstract: A reference signal generator circuit can be configured to provide a temperature-compensated voltage reference signal at an output node. The reference signal generator can include a diode-connected first FET device coupled between a supply node and the output node, and a flipped-gate transistor coupled between the output node and a reference node. The reference signal generator can include a bias current source configured to provide a bias current to the output node to adjust a current density in the flipped-gate transistor relative to a current density in the first transistor.
