Abstract: Embodiments herein describe correcting nonlinearity in a Digital-to-Time Converter (DTC) by relaxing a DTC linearity requirement, which results in the correction being co-adapted with a DTC gain calibration loop which can operate in parallel with a DTC integral nonlinearity (INL) correction loop. In one embodiment, the DTC gain calibration loop and the DTC INL correction loop are constrained when determining a nonlinearity correction code to improve the likelihood they converge. Once determined, the nonlinearity correction code can be combined with an digital code output by a time-to-digital converter (TDC) to generate a phase difference between a reference clock and a feedback clock.

Abstract: Systems and methods are provided for mechanical pretreatment of bipolar plates, for example, for plating electrodes in redox flow batteries. In one example, a method for disrupting surfaces of a bipolar plate may include pressing the bipolar plate between imprint plates, and removing the pressed bipolar plate from the imprint plates prior to use in a redox flow battery. In some examples, the pressed bipolar plate may include negative indentations from at least one of the imprint plates. In some examples, the imprint plates may be patterned meshes, such that the negative indentations may include patterns of asymmetric protrusions. In this way, the bipolar plate may be pretreated via pressing so as to reduce wear to manufacturing equipment (relative to other mechanical pretreatment processes, for example) while maintaining electrochemical performance of the redox flow battery.
