Abstract:
A gain- and offset- compensated (GOC) modification of sixth-order right-LUD wide bandpass switched-capacitor (SC) ladder filter is presented. At first, the conventional integrators in the filter are replaced with GOC SC integrators and the unswitched capacitors are split into two capacitors. Subsequently, the nominal op amps gain value A0 is taking into account in the capacitance sizing of some appropriately chosen capacitors. The influence of the variation of the finite gain A from its nominal value А0 on the filter passband response is considered.
