This paper describes the development of an analog active integrator applied in pulsed magnetic field measurement system. To meet precision requirement of the measurement system, the integral circuit was designed and the errors of real active integral circuit parameters were analyzed. Rationality of the proposition was proved and some relative parameters required for rational design so that errors can be kept within the permissible range were given, Test and experiment of the circuit demonstrate that this analog active integrator can meet design requirement of the pulsed magnetic field measurement system.
