The drive-sense circuit further includes a regulated current source circuit operable to generate a regulated current signal based on an analog regulation signal, where the regulated current signal is provided on a line to the variable impedance load to keep a load voltage on the line substantially matching the voltage reference signal, and where an impedance of the variable impedance load affects the regulated current signal. The drive-sense circuit further includes a current loop correction circuit operable to generate a comparison signal based on the voltage reference signal and the load voltage, where the comparison signal represents the impedance, and where the analog regulation signal is representative of the comparison signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Impedance detect drive sense circuit","description":"A drive-sense circuit coupled to a variable impedance load.
