Influence of op-amp nonidealities and switch-on resistances on SC integrator

An analysis of the stray-insensitive noninverting SC (switched-capacitor) integrator shows that the slewing time of the op-amp and the time constant connected with switch-on resistances determine the maximal sampling frequency of the network. The degradation of the frequency characteristics, if the sampling frequency is below the shown limit, is caused by switch-on resistances as well as by the finite gain-bandwidth product of the op-amp.<>
