A switch array is controlled to switch L1 between multiple electrodes according to a switching sequence, each electrode characterized by a load capacitance CL. L1 and CL form a resonator circuit in which signal energy cycles between L1 and CL at the signal frequency. The switch array switches L1 between a current electrode and a next electrode at a zero_crossing when signal energy in the energy transfer inductor is at a maximum and signal energy in the load capacitance of the current electrode is at a minimum. An amplitude control loop controls signal energy delivered to the L1CL resonator circuit, and a frequency control loop controls signal frequency/phase. In an example application, the resonant driver provides line drive for a mutual capacitance touch screen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Resonant line driver including energy transfer inductor for driving capacitive-load lines","description":"A resonant line driver for driving capacitive-loads includes a driver series-coupled to an energy transfer inductor L1, driving signal energy at a signal frequency through L1.
