Duplex sample forma baikatsudo switched capacitor filter

摘要

(57) Abstract It is desirable to be used as the output filter the baikatsudo switched capacitor filter in sigma delta digital/the analog converter. The switched capacitor filter uses the cross-linking switched capacitor circuit which sends electric charge to the condenser in both clock phase. As a result, while sending the same electric charge as the single sampler, just coefficient 2 can reduce the size of the condenser. The receptibility for the mismatching of the condenser by using the cross-linking switching circuit filter somewhere, is decreased substantially. In order for there to be delay of 1 clocks cycle around each looping which includes two filter steps, the clock phase which is impressed in the filter step is done, the police box guarantees the stability of the filter because of this.
