Latest Patents

One of Yongqing Ren's latest patents is titled "System and method for clock signal synchronization." This invention includes a data analyzer and a synchronized clock signal generator coupled to an RC oscillator. The data analyzer generates a digital control signal that represents the number of cycles of a reference signal of the RC oscillator during an eight-bit period of an incoming token packet. The synchronized clock signal generator uses this digital control signal to lock a clock signal to packets that share the same bit rate as the token packet.

Another significant patent by Ren is "Signal modulation scheme in class-D amplification and circuit therefor." This invention features a class-D amplifier that includes a logic circuit for controlling the operation of a switching bridge. The logic circuit transmits the differential mode of a differential pulse width modulation input signal while deleting a central portion of the common mode of the input signal. This deletion improves efficiency and reduces electromagnetic interference radiation. Additionally, preserving the pulses of the minimum pulse width ensures the proper operation of the switching elements in the switching bridge, thereby reducing distortion in signal amplification.
