Abstract: The present invention relates to an incremental analog to digital converter incorporating noise shaping and residual error quantization. In one embodiment, a circuit includes an incremental analog to digital converter, comprising a loop filter that filters an analog input signal in response to receiving a reset signal, resulting in a filtered analog input signal, and a successive approximation register (SAR) quantizer, coupled with the filtered analog input signal, that converts the filtered analog input signal to an intermediate digitized output of a first resolution based on a reference voltage, wherein the SAR quantizer comprises a feedback loop that shapes quantization noise generated by the SAR quantizer as a result of converting the filtered analog input signal; and a digital filter, coupled with the intermediate digitized output, that generates a digitized output signal of a second resolution, greater than the first resolution, by digitally filtering the intermediate digitized output.

Abstract: Sensor fusion for antenna tuning for wireless devices is provided to enhance antenna tuning and reduce power consumption of wireless devices. A sensor management component (SMC) obtains sensor information from sensors associated with a wireless device and determines position and/or orientation of the wireless device in relation to the user, and/or tracks movement of the wireless device. The SMC communicates sensor-based information relating to the position, orientation, and/or movement associated with the wireless device to a tuner management component (TMC) associated with a tuner component and a set of antennas. The TMC determines electrical measurements of the signal from the set of antennas, and determines a tuning setting for the set of antennas based on the sensor-based information and/or the electrical measurements. The TMC provides control information to the tuner component to adjust the tuning of the set of antennas based on the tuning setting.

Abstract: A circuit for a feedback system incorporates a gating mechanism to reduce flicker noise (e.g., a source for bias instability within a MEMS device) at a digital output. The gating mechanism generates a gating pulse with a delay period (e.g., a common, or fixed, delay including symmetrical rising and falling edge delays) that overrides internal delays (e.g., asymmetrical rising and falling edge delays) of a phase generator to prevent propagation delay (e.g., delay affected by jitter) from reaching subsequent feedback components (e.g., a digital-to-analog converter (DAC)) and contributing to the generation of flicker noise within the system.
