  • Patent number: 6956277
    Abstract: System and method for providing an electrical fuse having a p-n junction diode. A preferred embodiment comprises a cathode, an anode, and one or more links formed between the cathode and the anode. The cathode and the portion of the cathode adjoining the link are doped with a first impurity, preferably a p-type impurity. The anode and the portion of the link adjoining the anode are doped with a second impurity, preferably an n-type impurity. The junction of the first impurity and the second impurity in the link forms a p-n junction diode. A conductive layer, such as a silicide layer, is formed over the p-n junction diodes. In an alternative embodiment, a plurality of p-n junction diodes may be formed in each link. One or more contacts may be formed to provide electrical contact to the cathode and the anode.

  • Publication number: 20050218475
    Abstract: A fuse comprises a silicide element disposed above a substrate, a first terminal contact coupled to a first end of the silicide element, and a first metal line disposed above the silicide element and coupled to the first terminal contact. The fuse further comprises a plurality of second terminal contacts coupled to a second end of the silicide element, and a second metal line disposed above the silicide element and coupled to the plurality of second terminal contacts. The silicide element has a sufficient width that a programming potential applied across the first and second metal lines causes a discontinuity in the first terminal contact.

  • Patent number: 6639366
    Abstract: A power supply circuit for a cold-cathode fluorescent lamp (CCFL). The power supply circuit converts a DC voltage to a high AC voltage for driving the CCFL. The power supply circuit includes: a switch; a switch control circuit for controlling the switch; a transformer for stepping up the voltage; an energy-preserving unit coupled to the transformer and the DC voltage output circuit; a first diode coupled to the transformer, the energy-preserving unit, and the switch; and a decoupling capacitor coupled to the transformer for outputting the high AC voltage.

  • Publication number: 20030015971
    Abstract: An apparatus for driving a fluorescent lamp. The apparatus includes a dynamic driving voltage generator and an inverter. The dynamic driving voltage generator outputs a dynamic driving voltage. The inverter is coupled to the dynamic driving voltage generator and the fluorescent lamp for outputting a lamp-driving voltage according to the dynamic driving voltage. Wherein, the lamp-driving voltage is used to drive the fluorescent lamp, the lamp-driving voltage is fed back to the dynamic driving voltage generator, and the dynamic driving voltage generator outputs the dynamic driving voltage according to the lamp-driving voltage.
