摘要

Gain-and offset-compensated (GOC) modifications of four-phase inverting and no inverting switched-capacitor integrators based on the second-order Adams-Bashworth’s integration method are presented. Analytical expressions for the gain, phase and offset voltage errors are derived and compared with the corresponding errors of the earlier ones compensated integrators. The two pairs of GOC integrators are used as building blocks of a band pass biquad. The performances of the resulting filters are also compared.
