Patent number: 7463682Abstract: This invention presents a coding method for binary digits coding and its circuit for digits transmission. With this coding method, the binary digits are corresponding to a sequence of pulse groups. The binary digits “0” and “1” are corresponding to the two pulse groups with same defined number of pulses and with two special defined pulse frequencies respectively. The two pulse groups have the same defined number of pulses. The number is at least 2. The corresponding decoding method divides the sequence of pulse groups, according to the same defined number, into a set of pulse groups. The duration time of each pulse group is measured.

Patent number: 6747318Abstract: A method for fabricating buried channel NMOS devices and the devices themselves are disclosed. These buried channel NMOS devices are fabricated with a p-type substrate, an n-type implant in the top portion (approximately 400 to 1000 Å deep) of the substrate, and an insulating gate dielectric above the n-type implant. An n-type or p-type doped polysilicon gate electrode is formed on top of the insulating gate dielectric. The n-type implant region is doped in such a way that it is depleted of charge carriers when the device's gate electrode is at the same potential as the well (zero bias). When the gate electrode is biased +Ve with respect to the device's well substrate a conducting channel of mobile electrons is formed in a portion of the buried layer. This type of biasing is known as inversion bias since the charge carriers are of the opposite type than the p-well.Type: GrantFiled: December 13, 2001Date of Patent: June 8, 2004Assignee: LSI Logic CorporationInventors: Ravindra M.
