The error correction circuit portion includes an error-current-accumulating capacitor and a feedback circuit. The error-correction circuit performs error correction during a sampling operation by accumulating, at the error-current-accumulating capacitor, an error current output from an amplifier of the sample-and-hold circuit, and then applying, via the feedback circuit, a voltage boost to an input of the amplifier. The magnitude of the voltage boost depends on a voltage of the error-current-accumulating capacitor, and on various design parameters of the components of the circuit. By appropriately setting the design parameters, the magnitude of the fed-back voltage boost can be made to cancel out error due to charge injection and noise."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sample-and-hold circuit having error compensation circuit portion","description":"A sample-and-hold circuit having an error correction circuit portion that compensates for charge injection and noise.
