Latest Patents

One of Fei Xiao's latest patents is an innovative interface circuit. This circuit includes a current input circuit that receives an input current signal from a signal input terminal. An input voltage detection circuit compares the input voltage signal with a reference voltage and provides a detection signal to the current input circuit based on the comparison result. Additionally, a phase-inversion output circuit is connected to the current input circuit at the first node, generating a voltage conversion signal according to the voltage potential of the first node. A buffer circuit then shapes the voltage conversion signal to produce an output signal. The current input circuit pulls up the voltage potential of the first node when the detection signal indicates that the input voltage signal exceeds the reference voltage and the input current signal is greater than a reference current.

Another notable patent is related to a switching converter and its oscillator. This oscillator comprises a charging current generating circuit and a clock signal generator circuit, which generates a clock signal based on the charging current provided by the charging current generating circuit. The charging current generating circuit includes a variable resistor and a current limiting module. The current limiting module is designed to restrict the current value of the charging current to a preset level when the variable resistor is shorted or opened, thereby preventing drastic changes in the switching frequency of the circuit and enhancing system stability.
