    Abstract: Stacked layers of non-continuous opaque layer structures are disclosed herein that may be configured to block radiation such as visible light or other forms of light, while at the same time allowing penetration of ambient gases. In one example, such non-continuous opaque layer structures may be configured as stacked non-continuous metal layer structures that together fully block penetration of radiation while at the same provide sufficient open spaces between and/or within the metal layer segments of a given integrated circuit layer to meet maximum metal spacing rules. In another example, such non-continuous opaque layer structures may be configured as capacitive structures.

    Abstract: Embodiments of synchronous detection circuits and methods are provided for extracting magnitude and phase information from a waveform. One embodiment of a synchronous detection circuit includes a driver circuit, an analog-to-digital converter (ADC) and a controller. The driver circuit is configured to supply an input waveform at an input frequency to a load. The ADC is coupled to receive an output waveform from the load, and configured for generating four digital samples, each spaced 90° apart, for every period of the output waveform. The controller is configured for setting an oversampling rate (OSR) of the ADC, so that the ADC generates an integer number, M, of sub-samples for each digital sample generated by the ADC, where the integer number, M, of sub-samples is inversely proportional to the input frequency of the input waveform. The controller is further configured to use the digital samples generated by the ADC to extract magnitude and phase information from the output waveform.

    Abstract: A driver circuit includes two pull-up portions coupled respectively between VDD and first and second driver output nodes and two pull-down sections coupled respectively between ground and third and fourth driver output nodes. The driver circuit is configurable as an RS485 driver or a CAN driver. The active diodes in the pull-up sections are turned off when necessary to prevent unwanted reverse currents between the first and second output nodes and VDD. The active diodes in the pull-down sections are turned off when necessary to prevent unwanted reverse current between ground and the third and fourth output nodes.
