Title:
METHOD OF FILTERING ELECTRIC SIGNAL BY CHARGE MIGRATION TO SEMICONDUCTOR AND CAPACITOR FILTER WITH SWITCH USED THEREFOR
Document Type and Number:
Japanese Patent JPS5582464
Kind Code:
A
Abstract:
The process more particularly comprises introducing beneath the final storage capacitor C6 a quantity of charges equal to that located there during the processing of the preceding sample of the input signal, prior to the beginning of charge transfer from said capacitors to the means which convert the charges into a voltage, and distributing the charges between said capacitor and the preceding capacitor as a function of the capacitance values. The switched capacitor filter more particularly comprises, when it is looped, a circuit R permitting the application to the looping capacitor C4 of a voltage Vg+ DELTA Vs, while the foils of the other storage capacitors of the filter are connected to the voltage Vg.
