摘要：
A filter circuit switches a switching mechanism based on multipliers held in a data register DATA RGST as a digital data. Based on the output data of data register DATA RGST, a multiplication circuit M is arranged to have weights corresponding to a capacity of capacitance connected with a common analog input voltage X.
