Abstract
An adjustable attenuator circuit in which sampled electric charges are partially transferred from a sampling capacitor to a charge dividing capacitor during a short time within each sampling period, and electric charges stored in the charge dividing capacitor are additively transferred to an integrating capacitor or are discharged to ground according to the content of a weighting coefficient which determines the attenuation factor of the adjustable attenuator circuit.
