Takehiro Hata is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.

Latest Patents

Hata's latest patents include a voltage converter and a semiconductor integrated circuit. The voltage converter addresses the critical need to prevent a MOS transistor from being destroyed due to inrush current when a boost operation starts from a disabled state. This invention employs a third MOS transistor that turns off and a fourth MOS transistor that turns on to prevent current leakage from the output terminal to the input terminal. In the boost disabling state, the configuration ensures that the third MOS transistor turns on while the fourth turns off, effectively preventing current leaks due to parasitic diodes.

His second patent, a semiconductor device with a feedback circuit, enhances the stability of output voltage in switching power supply circuits. By incorporating a resistor and a capacitor, this invention improves the phase margin of the circuit, thereby increasing the response speed of the output voltage. The phase compensation circuit is designed to have a cut-off frequency that aligns with the resonance frequency of an inductor and capacitor, allowing for precise adjustments.
