Abstract
An integrator circuit () for use in a sigma-delta modulator () comprises a differential operational amplifier () with a first input node (E) and a second input node (E). The first input node (E) of the differential operational amplifier () is connected to a first current path () and the second input node (E) of the differential operational amplifier () is connected to a second current path (). A first controllable switch () is arranged between the second input node (E) of the differential operational amplifier () and the first current path (). A second controllable switch () is arranged between the first input node (E) of the differential operational amplifier () and the second current path (). A third controllable switch () is arranged between a reference potential (RP) and the first current path (). A fourth controllable switch () is arranged between the reference potential (RP) and the second current path ().
