Latest Patents
One of his latest patents is titled "Frequency synthesizing and back-end processing circuit and method thereof." This invention provides a fully digital frequency synthesizer that utilizes interpolation and a linear feedback shift register to synthesize frequencies. The circuit offers two options for digital and analog signals after digital-to-analog conversion. The selected signal is then mixed by the corresponding mixer, and a filter removes undesired noise to yield the desired synthesized frequency signal. This innovative frequency synthesizer simplifies circuit complexity while achieving high frequency resolution, surpassing conventional methods.
Another significant patent is the "Non-coherent frequency shift keying transmitter using a digital interpolation synthesizer." This invention replaces the traditional Phase Locked Loop (PLL) circuit with a digital frequency synthesizer for up-converting baseband signals to radio frequency signals. The system includes a micro processing unit that converts the baseband signal into an RF signal through various components, including a digital synthesizer and a digital-analog converter. This design eliminates unnecessary analog devices, enhancing stability and performance in RF signal transmission.
