ABSTRACT:
A switched capacitor network includes an input terminal (2) an output terminal (2), a series arrangement of a first and a second switching transistor, each having a control electrode (S.sub.1) for receiving a first (S.sub.1 ) and a second switching signal, respectively, and a capacitance between the junction point of the two switching transistors and a point of constant potential. The two switching transistors have a zone in common and the capacitance (S.sub.s) is exclusively constituted by the parasitic capacitance of the zone (17). This structure results in a switched capacitor network with an increased time constant.
