Abstract: The response of a Rogowski coil based current measuring circuit is often proportional to frequency. To correct for this a low pass or integrating function is applied to the response to linearize it. The low pass filter is made from real resistors and capacitors, and tolerances in their values significantly affect the estimate of current. This disclosure relates to a way of addressing such problems. This allows consumers of electricity to have confidence in the accuracy of, for example, their electricity meter.

Abstract: Embodiments of the disclosure can provide an optical charging system with an integrated sensor and power receiver. An electronic device (e.g., a wearable) can include an optical sensor for performing photometric measurements. A photodiode of the sensor can be shared and used for generating an electrical signal when exposed to a light source (e.g., LED) of a light power transmitter. The electrical signal can be conditioned by a power management circuit and can be used to charge a device battery. The light power transmitter can include a photodiode, which can be used for establishing a connection with the device using an optical signal emitted by a light source of the optical sensor. The light power transmitter can be power by, e.g., a USB connection. The intensity of the power transmitter light source can be regulated via a feedback signal from the device, based on the battery charging status.

Abstract: An integrated circuit may include a semiconductor die having a trench formed in a surface of the semiconductor die. One or more circuit components may be formed on the surface of the semiconductor die. The trench can extend into the semiconductor die next to at least one circuit component. The trench may surround the circuit component partially or wholly. The trench may be filled with a material having a lower bulk modulus than the semiconductor die in which the trench is formed.

Abstract: The disclosed technology generally relates to electrical overstress protection devices, and more particularly to electrical overstress monitoring devices for detecting electrical overstress events in semiconductor devices. In one aspect, an electrical overstress monitor and/or protection device includes a two different conductive structures configured to electrically arc in response to an EOS event and a sensing circuit configured to detect a change in a physical property of the two conductive structures caused by the EOS event. The two conductive structures have facing surfaces that have different shapes;

Abstract: Aspects of the present disclosure relate to decoding the output of a multi-turn magnetic sensor using a successive approximation technique to detect a number of turns of a magnetic target. A decoder circuit can decode a turn count of the multi-turn magnetic sensor by obtaining measurements at nodes that are determined from values of previous measurements.

Abstract: Optically isolated micromachined (MEMS) switches and related methods are described. The optically isolated MEMS switches described herein may be used to provide isolation between electronic devices. For example, the optically isolated MEMS switches of the types described herein can enable the use of separate grounds between the receiving electronic device and the control circuitry. Isolation of high-voltage signals and high-voltage power supplies can be achieved by using an optical isolator and a MEMS switch, where the optical isolator controls the state of the MEMS switch. In some embodiments, utilizing optical isolators to provide high voltages, the need for electric high-voltage sources such as high-voltage power supplies and charge pumps may be removed, thus removing the cause of potential damage to the receiving electronic device. In one example, the optical isolator and the MEMS switch may be co-packaged on the same substrate.

Abstract: A dither is an uncorrelated signal, usually pseudo-random noise injected into the input of an ADC such that a given input value of the wanted signal becomes spread over a plurality of codes. This reduces the effect of DNL and also smooths the integral non-linearity (INL) response of the ADC. The advantages of introducing dither could be obtained without having to perturb the signal input to the ADC. This avoids the introduction of additional components in the ADC. The dither can be applied to the components used to form a residue of the ADC stage within a pipelined converter. For example, a dither can be applied solely to a DAC part or different dithers can be applied to a ADC and DAC parts respectively. This allows greater flexibility of linearization of the ADC response and the formation of an analog residue by the DAC.
