Title:
METHOD FOR IMPROVING SENSITIVITY BY USING SHIELDING CAPACITY WITH REMODELED PARASITIC CAPACITY
Document Type and Number:
WIPO Patent Application WO/2022/173148
Kind Code:
A2
Abstract:
The present invention drives a plurality of capacitances of the present invention, including a shielding capacitance (Cin_sd), to minimize the variation of the voltage detected by a CDA signal line (200), thereby improving the resolution of an ADC and detects, in the form of a voltage, a capacitance (Cobj) which is generated and added between a CDA (100) and an object (20) according to the appearance of the object (20), thereby analyzing the detected voltage by using the ADC with improved resolution, to be thus able to detect the appearance of the object (20) more stably.
