Abstract: A gas sensor package is disclosed. The gas sensor package can include a housing defining a first chamber and a second chamber. An electrolyte can be provided in the first chamber. A gas inlet can provide fluid communication between the second chamber and the outside environs. The gas inlet can be configured to permit gas to enter the second chamber from the outside environs. An integrated device die can be mounted to the housing. The integrated device die can comprise a sensing element configured to detect the gas. The integrated device die can have a first side exposed to the first chamber and a second side exposed to the second chamber, with the first side opposite the second side.

Abstract: A phase-locked loop (PLL) comprising a multi-band oscillator and a memory configured to store control input for the oscillator. The PLL is operable in a calibration mode in which the PLL is configured to acquire a frequency controlled word (FCW) for the PLL corresponding to a frequency generated by the oscillator in response to a first control input threshold on a first band of the oscillator; generate a frequency corresponding to said FCW on a second band of the oscillator adjacent to said first band; identify a second control input causing the oscillator to generate said frequency corresponding to said FCW and store said second control input in memory.

Abstract: Techniques to generate two separate temperature independent reference voltages. The reference voltages can be generated using a chain of ΔVBE cells. A cross-quad ΔVBE-cell-based bandgap voltage reference can cancel out noise of associated current sources by forcing them to correlate. Several ΔVBE stages can be cascaded together to generate an appreciable PTAT component that can cancel the CTAT component from VBE. In some example configurations, only BJTs are used—without requiring use of an amplifier—to generate the bandgap voltages; in this way, extremely low noise voltage references can be generated. The PTAT and the CTAT voltages can be combined to generate a bandgap voltage of approximately VG0 or approximately 2VG0.

Abstract: Techniques are provided for an integrated circuit, current loop interface that can receive and extract a high-frequency digital communication signal from a low-frequency analog current signal using a complex impedance circuit. The complex impedance circuit can allow for low input impedance at the lower frequencies of the analog current signal and high input impedance at the higher frequencies of the digital communication signal.

Abstract: A device for providing a reset signal to one or more sequential logic circuits in an electronic system responsive to a supply voltage condition includes a first voltage detector circuit to generate a first pulse after the supply voltage rises to a first threshold voltage level. The device further includes a second voltage detector circuit to generate a second pulse after the supply voltage falls below a second threshold voltage level. The device additionally includes a latch circuit to store a first value based on the first pulse after the supply voltage rises to the first threshold voltage level, disable the first voltage detector circuit after storing the first value, reset to store a second value based on the second pulse after the supply voltage falls below the second threshold voltage level, and to disable the second voltage detector circuit after the resetting.

Abstract: An apparatus is provided which substantially removes a perturbation signal from a pulse density modulated signal representing a combination of a signal to be measured and a perturbation applied to the signal to be measured. The removal of the perturbation is done by subtracting a correcting signal from the pulse density modulated signal. This approach introduces very little delay as it can be implemented by simple logic gates. It also provided enhanced immunity from the effects of bit errors.

Abstract: Accurately measuring bio-impedance is important for sensing properties of the body. Unfortunately, contact impedances can significantly degrade the accuracy of bio-impedance measurements. To address this issue, circuitry for implementing a four-wire impedance measurement can be configured to make multiple current measurements. The multiple current measurements set up a system of equations to allow the unknown bio-impedance and contact impedances to be derived. The result is an accurate bio-impedance measurement that is not negatively impacted by large contact impedances. Moreover, bad contacts with undesirably large impedances can be identified.

Abstract: An electronic circuit includes parallel linear regulator circuits that support a range of different load currents. The electronic circuit includes a first linear regulator circuit coupled to an output node, a second linear regulator circuit coupled in parallel with the first linear regulator circuit and the output node, and a control circuit. The control circuit is configured to monitor the output node and to suppress or inhibit the second linear regulator circuit from supplying the output node when a representation of load power consumption is below a specified threshold. The first linear regulator circuit is configured to continue to supply a portion of the load power when the representation of load power consumption is above the specified threshold, and the control circuit may disable the second linear regulator circuit when the representation of load power consumption is below the specified threshold.

Abstract: System in package (SIP) modules are compact packages that include components such as processors, memory, sensors, and passive components on a single substrate. One low cost and compact way to integrate an antenna into a SIP module is to suspend an antenna in molding compound so that the antenna is embedded in the real estate of the molding compound layer. To embed the antenna, the molding compound is first deposited. A cavity can be cut in the molding compound to hold the antenna. The cavity can be filled with conductive material to form the antenna. Further molding compound can be deposited to cover the antenna and enclose the antenna in the molding compound layer. Ground structures can also be suspended in the molding compound. Such an embedded antenna can be particularly useful for radio applications.
