摘要:
A switched-capacitor amplifier arrangement and a method to amplify a signal are presented. A forward path has at least one switched capacitor (10) controlled by a clock signal, thus providing an amplification phase (1) of the forward path and an additional clock phase (2). A damping means (22) is connected to the forward path, the damping means being designed for attenuation of the signal peak at the beginning (2p) of the amplification phase. This avoids an undesired feed forward effect at the beginning of the amplification phase of an SC circuit.
