Latest Patents

Among his latest patents is a groundbreaking invention related to a switching element and a variable inductor. This invention allows for an inexpensive variable inductor with an inductance value that can be continuously changed without reducing the Q value. When a control voltage is applied to a control terminal of a MOS transistor from a power supply, a continuity region is formed in the channel, making the region between the main terminals conductive. As the control voltage changes, the length of the continuity region in the channel also changes, which in turn alters the length of the path area of the induced current flowing in an induced current film. Consequently, the amount of induced current can be increased or decreased, allowing for continuous changes in the inductance value of the coil.
