Latest Patents

Gaofeng Fan holds a patent titled "Audio artifact reduction in universal audio jack (UAJ) interface circuits." This invention focuses on circuit techniques that reduce or prevent audible artifacts in a Universal Audio Jack (UAJ) interface circuit. The technology enhances the handling of mis-configuration or mis-attachment of devices. The interface includes at least one terminal for accepting an audio input signal or providing an audio line output signal, which is coupled to an input or output of a first audio circuit. This first audio circuit operates from a low voltage domain and is responsible for receiving the audio input signal or providing the audio line output signal. A second circuit operates from a higher voltage domain, and a switching circuit couples the terminal to this second circuit. The output is slew-rate controlled to manage the transition time of the output, effectively avoiding audible artifacts that could be generated by the switching circuit.
