Abstract
A method and a device having amplification and noise reduction capabilities, the device may include (a) an amplifier; (b) an input circuit that includes multiple sampling circuits, (c) an error capacitor that is arranged to be charged by the amplifier, during a noise integration period, to an error voltage that is indicative of noise generated as a result of a sampling of first and second signals; and (d) a feedback circuit that is arranged to provide to the second input of the amplifier and in proximity to a beginning of second phase of operation, a feedback signal that represents the error voltage and thereby at least partially compensate for the noise.
