Abstract: A switched capacitor voltage regulator (SCVR) design, such as a continuous capacitive voltage regulator (C2VR) design, may use capacitors and switches to provide improved cost and space efficiencies. A remote sensing circuit may be used to improve C2VR performance. By adding a remote sensing circuit to the regulation feedback loop within the C2VR circuit design, the C2VR circuit may provide improved accuracy in voltage regulation, such as by providing a correction based on the voltage error between the remote-sensed voltage and the reference target. The remote sensing circuit may also provide transient information for under-voltage detection at an output terminal. This detected transient may become an alternating current (AC) portion of the under-voltage detection threshold, which improves the ability of the C2VR circuit to provide early detection for any under-voltage fault.

Abstract: Techniques and mechanisms for determining a mode of operation of a switched capacitor voltage regulator (SCVR). In an embodiment, a controller supports multiple modes of operation of the SCVR, wherein the modes each correspond to a different respective sequence of switch states of a converter core of the SCVR. One of the modes is to provide boost voltage regulation with the SCVR. The controller transitions seamlessly and autonomously between two modes based on respective reference switch states of the two modes. In another embodiment, a mode transition is performed based on a signal which a control sensor generates based on a rate of switch events of the voltage regulator, and predetermined reference information indicating current characteristics of the voltage regulator.

Abstract: Embodiments described herein may include apparatus, systems, techniques, and/or processes that are directed to multiphase power converters and how current level outputs of each phase circuit are calibrated. The multiple phase circuits are grouped into multiple subsets, wherein one phase circuit of each subset is designated as a reference phase circuit. The reference phase circuits of each subset are calibrated together, using, for example, a closed loop daisy chain technique where each reference phase circuit calibrates their current output to the current output of the previous phase circuit, or alternatively, a current averaging technique where each reference phase circuit balances their current output to the average output of the reference phase circuits.

Abstract: A circuit can process a sample of a signal to emulate, simulate, or model an effect on the signal. Thus, an emulation circuit can produce a representation of a real-world signal transformation by processing the signal according to one or more signal processing parameters that are characteristic of the real-world signal transformation. The emulation circuit can apply analog signal processing and/or mixed signal processing to the signal. The signal processing can comprise feeding the signal through two signal paths, each having a different delay, and creating a weighted sum of the outputs of the two signal paths. The signal processing can also (or alternatively) comprise routing the signal through a network of delay elements, wherein a bank of switching or routing elements determines the route and thus the resulting delay.
