Abstract
The present invention involves replicating the existing state in a system to store in memory for detecting variations due to added factors. Based on the stored values in the memory, changes in the system are detected. A certain electronic circuit is used to extract these replicated values, and the values output from the electronic circuit are fed back. The adjusted input variables are then extracted and stored in memory.
Claims1
A capacitive detection device, comprising:
- capacitive detection area (CDAs) formed from a conductor and an independent area;
- sensing signal lines connected to the CDAs;
- an operational amplifier within a semiconductor integrated circuit (IC);
- a digital-to-analog converter (DAC) connected to an input terminal of the operational amplifier;
- and
- the sensing signal lines connected to other input terminal of the operational amplifier for detecting an added capacitance from the sensing signal lines when a drive voltage is applied to a capacitor formed on the sensing signal lines.
