The first stage includes first and second NMOS input transistors coupled between an enabling transistor and respective first and second cascode devices to receive the reference voltage and the image charge voltage signal. A first auto-zero switch is between a gate of the first NMOS input transistor and a first node. The first node is between the first NMOS input transistor and the first cascode device. A second auto-zero switch is between a gate of the second NMOS input transistor and a second node. The second node is between the second cascode device and a second PMOS transistor. A voltage difference between the first and second nodes during an auto-zero period reduces an amount of kickback that occurs during an ADC period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Comparator for double ramp analog to digital converter","description":"A comparator includes a first stage coupled to compare a reference voltage to an image charge voltage signal.
