Latest Patents

One of Tokuda's latest patents is a power supply circuit and power supply control method. This invention includes a coil with first and second ends, where a supply voltage is applied to the first end. It features a first switching element connected between the second end of the coil and ground, along with a second switching or diode element that supplies current to a load after rectifying the current based on the voltage generated at the connection of the coil and the first switching element. Additionally, it incorporates a driver circuit that switches at least the first switching element, a third switching element connected in series to the load, and a power supply stop circuit that switches off the first element to stop supplying power to the load in response to an external signal.

Another notable patent is a voltage-current conversion circuit. This circuit outputs a current corresponding to the difference between a first input voltage and a second input voltage. It includes a first current-mirror circuit supplied with the first input voltage and a second current-mirror circuit supplied with the second input voltage. The design features a resistor connected between one of the pair of transistors of the first current-mirror circuit and one of the transistors of the second current-mirror circuit, along with a third current-mirror circuit that has current source transistors supplying current to the respective pairs of transistors.
