The capacitor, the inductor and the cross-coupled switches form an oscillator. The control switch controls operation of the oscillator between an ON state and an OFF state in response to a data signal to be communicated across an isolation barrier. The inductor may be formed from a winding of an isolation transformer, which reduces component count as compared to a system that provides a separate inductor. Other embodiments may include a current-supplying kickstart circuit and a shorting transistor that can speed transition between the ON and OFF states."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and structures to generate on/off keyed carrier signals for signal isolators","description":"An oscillator for a signal isolator system includes a capacitor and an inductor connected in parallel, two pairs of cross-coupled switches and a control switch.
