Document Type and Number:
Japanese Patent JPS647524
Kind Code:
B2
Abstract:
A switched capacitor filter is designed utilizing two switched capacitor charge pumps connected in series. These two charge pumps operate with different clock frequencies thereby allowing charging of a storage capacitor at a higher frequency, thereby decreasing incremental voltage steps during the charging of the storage capacitor, resulting in the generation of a smoother exponential voltage rise.
