  • Publication number: 20060261898
    Abstract: An analog semiconductor integrated circuit has an analog circuit, a PMOS and a bias adjustment circuit. The gate of the PMOS is the output section of an open drain system, and is connected to an internal node on the output side of the analog circuit. The bias adjustment circuit is connected to the internal node, and allows adjustment of the bias current in accordance with the fuse disconnection number. The relationship between the voltage when a fixed current flows to an input terminal and the fuse disconnection number that allows the optimum bias current to flow to the output section of the analog LSI is checked by using a plurality of sample analog LSIs having different threshold voltages. The voltage is measured by causing a fixed current to flow to the input terminal of a non-sample analog LSI, and the fuse disconnection number corresponding with this voltage is obtained. Thus, the fuses in the bias adjustment circuit are disconnected.

  • Patent number: 6501412
    Abstract: Quantizers included in an analog-to-digital converter each compare an input analog voltage with a reference voltage to convert the analog voltage to digital data and output a voltage representative of a difference between the analog voltage and a voltage corresponding to the digital data. In each quantizer includes a comparator comparing the analog voltage with the reference voltage to output a result of comparison. An amplifier amplifies a voltage representative of a difference of the analog voltage from the reference voltage. Another amplifier inverts the voltage representative of the difference of the analog voltage from the reference voltage and amplifies the inverted voltage. A couple of switches are respectively connected to the one and the other amplifier for selecting either one of the output voltages of the amplifiers in accordance with the result of comparison.

  • Patent number: 6091380
    Abstract: A 3-electrode, surface-discharge type plasma display is capable of offsetting a radiation fields which is generated at the time of displaying, to reduce radiation noises. To drive the plasma display, an X-electrode and a Y-electrode are separated to an even number (2m) and an odd number (2m-1), respectively. During a resetting period and an addressing period, pulse voltage is applied to the even-numbered and odd-numbered electrodes at the same time, whereas in a sustained discharge period, the phase of the pulse voltage applied to the even-numbered electrode is delayed by 180 degrees from that applied to the odd-numbered electrode.
