Publication number: 20160098118Abstract: The present invention is related to a capacitive touch device and excitation signal generating circuit and method thereof. The excitation signal generating circuit is connected to multiple sensing traces of the capacitive touch device, and has a storage unit storing at least one set of digital data. Each set of digital data is corresponding to a frequency. The PDM signal generator reads the set of digital data and converts the read set of digital data to a PDM signal according to the frequency of the read set of digital data. The PDM signal is recovered to an analog excitation signal since the PDM signal passes through a current transmission path, which is equivalent to a low pass filter. Therefore, the present invention can decrease a distortion of the sensing signal to increase accuracy of the sensing signal and to save power.Type: ApplicationFiled: August 13, 2015Publication date: April 7, 2016Applicant: ELAN MICROELECTRONICS CORPORATIONInventors: Chia-Hsing Lin, Han-Wei Chen, Jyun-Yu Chen

Patent number: 7386403Abstract: A method and a system for charging management are applied in an electronic device. The system includes a sensing unit, a detecting unit, a signal output unit, a receiving unit and a processing unit. By the method, when the sensing unit senses an external power source inputted to the electronic device, the detecting unit detects a current electric quantity of a battery of the electronic device.
