  • Patent number: 10693483
    Abstract: Adaptive toggle number compensation techniques for reducing data dependent supply noise in DACs are disclosed. Various embodiments are based on setting a certain target toggle number for a plurality of DAC units used to convert at least a portion of a digital data sample and then applying various adaptive techniques to try to achieve the target toggle number in converting the data sample from digital to analog domain. Adaptive toggle number compensation techniques described herein try to reduce data dependent supply noise by deliberately limiting, to a certain target number, the number of DAC units that undergo a switch from the digital input of 1 to 0 or from 0 to 1 in converting a digital data sample. Compared to the conventional dummy signal generation approach, such adaptive toggle number compensation techniques may provide significant savings in terms of power consumption of a DAC.

  • Patent number: 10682715
    Abstract: A method for electroerosion machining includes providing an electrode assembly comprising an electrode body having a tube-shaped body that defines a hollow interior and one or more inserts affixed to the electrode body to form a cutting surface on the electrode assembly, positioning the electrode assembly adjacent a workpiece to be machined, and providing power to the electrode assembly so as to energize the electrode assembly, with the electrode assembly and the workpiece being at opposite electrical polarities. The method also includes advancing the electrode assembly through the workpiece, with a working gap being maintained between the inserts and the workpiece across which a pulse electric current is passed to remove material from the workpiece, wherein, upon advancing the electrode assembly through the workpiece, a core is formed that is completely separated from a remainder of the workpiece and is contained within the hollow interior of the electrode body.

  • Patent number: 10644716
    Abstract: A multi-path dual-switch DAC refers to implementing multiple paths in a switch driver and only two switches in a DAC stack of a DAC unit. In addition to multiple paths configured to improve the driving ability of the input signals, the switch driver of a multi-path dual-switch DAC unit includes two or more logic gates configured to act as multiplexers combining some of the output signals from different paths. The use of such logic gates enables using only two switches in the DAC stack unit to receive the data. Furthermore, optionally, additional logic gates may be used to combine some other output signals from different paths to generate dummy signals, thus providing internal dummy logic. The multi-path dual-switch DACs described herein may advantageously use half-clock rate and reduce or eliminate supply modulation issues, while also reducing power consumption and improving linearity compared to traditional DAC architectures.
