    摘要: A semiconductor integrated circuit has a plurality of capacitor cells, and each capacitor cell has an upper electrode and a lower electrode. These electrodes are respectively connected to an upper electrode wiring and a lower electrode. When, for example, the upper electrode is connected to the upper electrode wiring and the electrode wiring is located at a side of the lower electrode of another capacitor cell or a side of the lower electrode wiring connecting these electrodes, a shield wiring is provided between the upper electrode wiring and the adjacently-located lower electrode of the other capacitor cell or between the upper electrode wiring and the adjacently-located lower electrode wiring. Thus, with this shield wiring, the capacitance coupling between each wiring of the capacitor cells and each upper electrode or each lower electrode of the capacitor cells are effectively suppressed.

    摘要: In a charge redistribution type A/D converter, an input-side capacitor terminal and a comparator-side capacitor terminal are connected through first and second analog switches to a fixed-voltage supply circuit, and the input-side capacitor terminal is connected through a third analog switch to the outside. Immediately before sampling an analog signal, the first and second analog switches are closed while the third analog switch is opened, according to a RESET signal. Thereby, fixed voltages are supplied to the input-side capacitor terminal and the comparator-side capacitor terminal, respectively, and charge stored in a weighting capacitor unit is initialized to a predetermined value.

    摘要: The present invention provides a serial/parallel A/D converter which is capable of performing a high-speed and high-accuracy operation even in the case where an analog input voltage Vin greatly varies in a period between a previous sampling period in which the analog input voltage is held and the next sampling period, when converting the analog input voltage Vin input into a digital value. This serial/parallel A/D converter includes a lower-order reference voltage initializing circuit 8 for initializing a lower-order reference voltage to an initialization voltage Vrc 23. The initialization voltage Vrc 23 is generated as the lower-order reference voltage in an arbitrary period from the start of sampling of the analog input voltage until the start of a comparison operation for the lower-order reference voltage, the value of the lower-order reference voltage is changed from the value of the initialization voltage to a voltage value which is decided on the basis of higher-order code selection signals P0C-P3C from a higher-order code selecting circuit 14, and the value of the lower-order reference voltage which is decided on the basis of the higher-order code selection signals P0C-P3C is compared with the value of the analog input voltage.

    摘要: It is constructed so as to detect a joint movement position of a robot arm by a position detector and a joint movement speed is calculated from change amounts of the joint movement position and elapsed time and is compared with an allowable movement speed and unlocking and locking of a brake are controlled so that the joint movement speed of an arm at the time of brake unlocking becomes within a constant value even when a shape, an attitude and a load condition of the robot arm vary. Therefore, movement work of the arm by the brake unlocking can be performed alone and a robot with high safety can be obtained.

    摘要: A sub woofer system is constituted of a real time digital signal processing part 5 that includes an A/D converter 5a, a low pass filter block 5b, a delay block 5c, and a D/A converter block 5d, an analog power amplifier 6 and a speaker 7. The length of delay time of the delay block 5c is set so that the length of group delay time of the digital signal processing part 5 may equal an integral multiple of the length of time corresponding to one wavelength of the crossover point frequency between the digital signal processing part 5 and a main speaker 4. The signal processing is performed under the conditions that have been set as such. In this case, a construction is made up wherein the length of a group delay time produced in the digital type real time digital signal processing part can be set to a given value. By this construction, it is possible to provide a sub woofer system which can improve the phase interference between the main speaker and the sub woofer system at the crossover point between the two.
