Filed:

Sep 30, 2003

Appl. No.:

10/676531

Inventors:

Dinh Quoc Nguyen - San Jose CA, US

Assignee:

National Semiconductor Corporation - Santa Clara CA

International Classification:

H01L023/62
H01L029/74
H01L031/111
H02H009/00

US Classification:

257173, 257111, 257162, 257168, 257355, 257356, 257357, 257546

Abstract:

A bi-directional silicon controlled rectifier structure provides electrostatic discharge (ESD) protection against both positive and negative voltage spikes. The structure utilizes a pair of wells, n+ and p+ regions formed in both wells, a first ring formed around the junction between the first well and the semiconductor material, and a second ring formed around the junction between the second well and the semiconductor material.

Appl. No.:

12/179458

Inventors:

Chang Chia Hsiao - San Jose CA, US
Dinh Nguyen - San Jose CA, US

Assignee:

National Semiconductor Corporation - Santa Clara CA

International Classification:

H03F 3/26

US Classification:

330267, 330263

Abstract:

A unity gain buffer is provided. The unity gain buffer includes two complementary pairs of emitter followers and two bias current sources. The top bias current source is arranged to provide a bias current so that, if the input voltage is greater than zero, the bias current provided by the top current source increases at the input voltage increases. The bottom current source is arranged to provide a bias current so that, if the input voltage is less than zero, the bias current provided by the bottom current source decreases as the input voltage decreases.

US Classification:

36167908, 36167958, 36167947

Abstract:

The adaptive computing system described herein may generally include a modular control, switching, and power supply architecture. In particular, the adaptive computing system may provide a platform supporting multiple independent desktop computer modules that occupy less physical space than a standalone commercial computer, provide performance density comparable to current server solutions, and address concerns relating to stability, safety, productivity, performance, assembly, service, and other factors important to diverse desktop computer user communities. Moreover, mechanical, electrical, and functional components associated with the adaptive computing system may have various certifications or otherwise be relied upon to demonstrate compliance with criteria in regulatory, environmental, consumer safety, and other contexts.

International Classification:

H04L 29/08
H04W 88/02
H04L 29/06

Abstract:

The disclosure relates to a portable computing device configured to selectably switch between a wired zero client mode in which the portable computing device operates as a terminal for a host computer via a wired communication channel, a wireless zero client mode in which the portable computing device operates as a terminal for the host computer via a wireless communication channel, and a local mode in which the portable computing device operates independently from the host computer. The portable computing device may include one or more zero client processors that facilitate operation in the wired or wireless zero client mode and one or more local control processors that facilitate operation in the local mode. The portable computing device may include input devices used to receive inputs for the host computer during the wireless or wired zero client modes or for the local control processors during the local mode.
