abstract:An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator. In its most basic implementation, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period (the run-up period).
This articlediscusses the principleandlinearityofchargesensitiveamplifier. The result of simulation and the property of both charge integratingADC and dataacquisitionsystem were described.
