Latest Patents

One of Okumura's latest patents is an integrated circuit device that includes CMOS tri-state drivers suitable for powerdown. This innovative device is designed to effectively shut off the power supply during a powerdown mode. It connects to three power supplies: a first (ground) power supply, a second power supply that continuously provides power, and a third power supply that halts power supply during the powerdown mode. The device features a controller and a CMOS tri-state driver, which consists of a series connection of a P-channel MOS transistor and an N-channel MOS transistor. The design ensures that during the powerdown, the output of the CMOS tri-state driver remains in a high-impedance state, effectively preventing leakage current from flowing into the P-channel MOS transistor.
