Latest Patents

One of Tsukazaki's latest patents is an analog switch circuit. This circuit includes an analog switch composed of a first P-channel MOS transistor and a first N-channel transistor, with a gate that receives a control signal. The circuit features a comparison circuit that compares the potentials of a first input-output terminal and a second input-output terminal, conveying the higher potential to a well where the first P-channel MOS transistor is formed. Additionally, it includes a first potential conveying circuit that conveys the potential of the well to the gate of the first P-channel MOS transistor when the analog switch is in the OFF state. A second potential conveying circuit operates based on a control signal to turn off the first P-channel MOS transistor, while a third potential conveying section turns it on.

Another significant patent is a logic circuitry-implemented bus buffer. This bus buffer has a controller that generates several control signals. It features a first terminal for inputting a first-directional signal and outputting a second-directional signal, and a second terminal for the opposite. The bus buffer includes a first-directional signal processor with a first internal circuit and a first output buffer, as well as a second-directional signal processor with a second internal circuit and a second output buffer. The design incorporates input buffers that deactivate the internal circuits and output buffers using control signals, which helps to decrease current and achieve low power consumption.
