Abstract: Apparatus and methods for programmable low dropout (LDO) regulators for radio frequency (RF) electronics are provided herein. In certain configurations, an LDO regulator for generating a programmable output voltage includes a regulation field-effect transistor (FET) having a drain electrically connected to the LDO regulator's output, an error amplifier that controls a gate of the regulation FET, a feedback circuit that provides a feedback signal to an inverting input of the error amplifier, an output capacitor electrically connected to the LDO regulator's output, and an alternative discharge circuit. When the output voltage of the LDO regulator is programmed from a high voltage level to a low voltage level, the alternative discharge circuit activates to discharge the output capacitor to improve the LDO regulator's transient response.

Abstract: Features are disclosed for processing a user utterance with respect to multiple subject matters or domains, and for selecting a likely result from a particular domain with which to respond to the utterance or otherwise take action. A user utterance may be transcribed by an automatic speech recognition (“ASR”) module, and the results may be provided to a multi-domain natural language understanding (“NLU”) engine. The multi-domain NLU engine may process the transcription(s) in multiple individual domains rather than in a single domain. In some cases, the transcription(s) may be processed in multiple individual domains in parallel or substantially simultaneously. In addition, hints may be generated based on previous user interactions and other data. The ASR module, multi-domain NLU engine, and other components of a spoken language processing system may use the hints to more efficiently process input or more accurately generate output.

Abstract: Simulation and verification are critical to analyzing a semiconductor design using design rule checking (DRC) to verify design rules for manufacturing (DRM). The efficient use of computational resources including runtimes and resource requirements is a key component of the analysis. A virtual hierarchical layer (VHL) with shapes is generated for the design analysis of a design, including cells and hierarchical design levels. A cell and multiple instances of the cell are identified in the design. A VHL based on polygons overlapping the cell is generated in response to an algorithmic operation. The VHL shapes are propagated to subsequent algorithmic operations. The algorithmic operations update the VHL shapes. Shapes are filtered out of the VHL shapes as part of the updating. The VHL shapes are propagated through a chain of operations.
