Filed:

Oct 14, 2003

Appl. No.:

10/686545

Inventors:

James P. Baukus - Westlake Village CA, US
Paul Ou Yang - San Jose CA, US

Assignee:

HRL Laboratories, LLC - Malibu CA
Promtek - Santa Clara CA

International Classification:

H01L023/04

US Classification:

257698, 257700, 257774, 438622

Abstract:

A multilayered integrated circuit and a method of designing a multilayered integrated circuit are provided. The circuit comprises at least two conductive layers and extraneous conductive lines placed in the conductive layers. The extraneous conductive lines are made of a material which is the same as the material in the conductive layers and have dimensions which are the same as the dimension of the material in the conductive layers. The extraneous conductive lines perform functions which are unnecessary to the operation of the integrated circuit and are undistinguishable from the functional conductive lines, thus burdening the work of a reverse engineer. The method of designing the multilayered circuit comprises a step of providing a computer generated representation of the extraneous conductive lines.

International Classification:

H04B 1500
H04K 100
H04L 2730

US Classification:

375207

Abstract:

A method for demodulating a received spread-spectrum signal using a minimum-shift-keyed (MSK) receiver. Using the method, an in-phase-component signal and a quadrature-phase-component signal are generated from a received spread-spectrum signal. The in-phase-component signal and the quadrature-phase-component signal are then processed and combined in such a way as to estimate data of the received-spread-spectrum signal.

International Classification:

H04J 300

US Classification:

370 321

Abstract:

An integrated echo canceling multiplexor is provided which comprises an echo canceler for receiving DS1 signals for canceling echo in the DS1 signal and producing an echo-free digital logic signal. A first performance monitor is coupled to the echo canceler for receiving the echo-free digital logic signal and determining the quality of the signal. A multiplexor-demultiplexor is further coupled to the echo canceler for receiving the echo-free digital logic signal and producing a DS3 signal. Additionally, a second performance monitor is coupled to the multiplexor-demultiplexor and receives the DS3 signal and determines the quality of the signal.
