    摘要: A power generation circuit generates and stores electric power utilizing electromagnetic wave energy. The power generation circuit has one of an antenna or a coil that receives an electromagnetic wave. A rectifying circuit is formed on a silicon substrate and rectifies a signal from the antenna or the coil. A storage circuit stores an output power obtained from the rectifying circuit for driving a load. A MOS transistor has a source and a drain connected to an output of the storage circuit and the load, respectively, so that the load is connected to the storage circuit in accordance with a threshold voltage of the MOS transistor.

    摘要: A power generation circuit has one of an antenna or a coil that receives an ambient radio wave. A rectifying circuit is connected to the antenna or the coil for rectifying a signal from the antenna or the coil receiving the ambient radio wave. A booster circuit is connected to and boosts an output of the rectifying circuit. A storage circuit is connected to the booster circuit and stores an output power obtained from the rectifying circuit for driving a load without the use of a power source or a battery. A switching circuit is operable in an ON-state thereof to connect the storage circuit to the load when a voltage of the storage circuit is equal to or greater than a preselected voltage.

    摘要: In an accelerometer, the stress is detected through electric amplification with the use of detecting elements 411-434 having an amplification function arranged on beams 3 and, with the use of a differential amplifier circuits 510 formed on the support base 1, an acceleration component in a detection axis direction to which the stress is applied is outputted as the differential mode and acceleration components in the other axis directions are outputted as the common mode, so that each axis sensitivity ratio between the detection axis sensitivity and the other axis sensitivities is enhanced largely.
