Latest Patents

One of Shih-Hsin Lin's latest patents is a feedback system and associated signal processing method. This invention provides a feedback system that includes a mixing circuit, a forward circuit, a feedback circuit, a feedback gain circuit, and a control circuit. In the operations of this feedback system, the mixing circuit generates a mixed signal based on an input signal and a feedback signal. The forward circuit processes the mixed signal to produce an output signal, while the feedback gain circuit and feedback circuit generate the feedback signal based on the output signal. The control circuit determines the feedback gain of the feedback gain circuit according to the gain of the forward circuit.

Another significant patent is related to an audio device and an electronic device that incorporates this audio device, along with an audio signal processing method. This audio device is designed to receive and process a digital audio signal, ultimately outputting an analog audio signal. It consists of an adder, a digital-to-analog conversion circuit, an amplifying circuit, a voltage detecting circuit, and an offset compensating circuit. The voltage detecting circuit monitors the supply voltage received by the amplifying circuit, while the offset compensating circuit generates a DC offset compensation value based on this supply voltage. The adder combines the digital audio signal with the DC offset compensation value to produce an added signal, which is then converted into an analog audio signal by the digital-to-analog conversion circuit. The amplifying circuit amplifies this converted analog signal, effectively reducing pop noise caused by a DC offset.
