Abstract:
Virtual ground sensing circuits, control circuit, electrical systems, computing devices, and related methods are disclosed. A control circuit includes a virtual ground sensing circuit configured to provide a virtual ground to a conductive line. The virtual ground sensing circuit is further configured to selectively operably couple the conductive line to a sense node of a sense circuit, wherein the sense node having a sense node capacitance less than a capacitance of the conductive line. Further, virtual ground sensing circuit is configured to compare a sense node voltage to a reference voltage.
