Latest Patents

One of Chen's most notable patents is titled "Circuit for Detecting Maximal Frequency of Pulse Frequency Modulation and Method Thereof." This invention describes a sophisticated circuit that includes an oscillator-controlling unit, a delay circuit, and a master-slave register. The oscillator-controlling unit is directly connected to an oscillator, generating pulse frequency modulation signals through its dual pulse-generating modules. The second half of the module connects to a delay circuit, while the master-slave register, which features a clock, input end, and output end, effectively manages the signal processing.

Another key patent by Chen is the "Circuit and Method for Switching PFM and PWM." This invention outlines a method of dynamically switching between pulse frequency modulation and pulse width modulation signals. It starts by analyzing the output voltage of a power transistor to create a corresponding pulse frequency modulation signal. If this signal achieves its maximal frequency, the initial pulse width modulation signal undergoes adjustments to match the pulse frequency modulation in width, ensuring consistent signal performance.
