20110095788 | High-speed comparator with asymmetric frequency response - A comparator to provide an output voltage indicative of comparing an input voltage with a reference voltage, where the comparator has an asymmetric frequency response. With an asymmetric frequency response, the bandwidth of the input voltage may be greater than the bandwidth of the reference voltage. A comparator includes a differential pair of transistors coupled to a current mirror and biased by a current source, where in one embodiment, a capacitor shunts the sources of the differential pair. In a second embodiment, a capacitor couples the input voltage port to the gates of the current mirror transistors. In a third embodiment, the comparator utilizes both capacitors of the first and second embodiments. | 04-28-2011 |

20130083935 | METHOD FOR TESTING AN AUDIO JACK OF A PORTABLE ELECTRONIC DEVICE - A method for testing an audio jack of a portable electronic device is provided. The audio jack has a first sound channel, a second channel and a microphone. First, the first sound channel is controlled to play a designated audio file by the portable electronic device. Nest, the played sound is recorded into another recorded audio file by the portable electronic device at the same when the first sound channel is playing the designated audio file. Afterwards, the recorded audio file is played via the second sound channel by the portable electronic device. Finally, it is determined whether the another recorded audio file that is played matches with the designated audio file, and if the audio files match, it represents that the first sound channel, the second sound channel and the microphone have normal function. | 04-04-2013 |

20130142346 | AUDIO TESTING SYSTEM AND AUDIO TESTING METHOD FOR DEVICE UNDER TEST - An audio testing system and an audio testing method for an electronic device under test are provided. The audio testing method includes the following steps. A testing audio is sent through a testing audio sending end of a testing device. An electronic device under test is controlled to perform recording through an audio receiving end, so as to generate an under-testing audio. After the recording is completed, the device under test controlled to playback the under-testing audio from one of both-side audio sending ends to perform recording through the testing audio receiving end, and calls an audio analyzing process to generate a first testing result. The device under test controlled to playback the under-testing audio from the other one of the both-side audio sending ends to perform recording through the testing audio receiving end, and calls the audio analyzing process to generate a second testing result. | 06-06-2013 |
