With a total of 2 patents to his name, Mishima continues to push the boundaries of innovation in his industry.
Latest Patents
Mishima's latest patents include a DC-DC converter and a semiconductor integrated circuit designed for cable voltage drop compensation. The DC-DC converter efficiently converts a DC input voltage from a power supply to an output voltage with a different potential. It features a control circuit that manages a switching element based on the potential difference between a feedback voltage and a predetermined reference voltage. Additionally, a current supply circuit ensures a predetermined current flow, while a voltage correction circuit adjusts the reference or feedback voltage based on external resistance information.
The semiconductor integrated circuit includes a current mirror with a specific input-output ratio, utilizing a first transistor to receive input current and a second transistor to output current. An output transistor generates a reference voltage according to the output current of the current mirror. This innovative design allows the output current to exceed the input current while maintaining a balanced collector region area between the transistors.
