The first switch has a control terminal and makes the output voltage equal to the input voltage when switching on. The second switch is coupled to a first terminal of the capacitor and a first level. The third switch is coupled to a second terminal of the capacitor and a second level. The fourth switch is coupled to the first terminal of the capacitor and the control terminal. The fifth switch is coupled to the control terminal and the second level. The voltage buffer has large input impedance, and has an input receiving the input voltage, an output providing a voltage equal or close to the input voltage. The sixth switch is coupled to the second terminal of the capacitor and the output of the voltage buffer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sampling circuit and sampling method","description":"A sampling circuit for sampling an input voltage and generating an output voltage, comprising six switches, a capacitor and a voltage buffer.
