The buck converter comprises of a control block that controls a first p-channel MOSFET switch, and a second n-channel MOSFET switch. The p-channel MOSFET switch and the n-channel MOSFET switch provide a sense signal utilizing parasitic bipolar junction transistors. The p-channel MOSFET provides a sense current for the pnp parasitic bipolar junction transistor, The n-channel MOSFET provides a sense current for the npn parasitic bipolar junction transistor. The sense current is stored on a capacitor, and establishes an adaptive offset adjustment to a zero-cross comparator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive threshold of a zero crossing comparator","description":"A buck converter device with a zero-cross comparator with an adaptive threshold.
