Publication number: 20080265906Abstract: A method and apparatus for testing an integrated circuit core or circuitry external to an integrated circuit core using a testing circuit passes a test vector from a parallel input of the testing circuit along a shift register circuit. The shift register circuit is configured to bypass one or more cores not being tested and to provide the test vector to a core scan chain of the core being tested. The bypassed cores are configured such that the associated shift register circuit portion is driven to a hold mode in which storage elements of the shift register circuit portion have their outputs coupled to their inputs. This method provides holding of the shift register stages when a core is bypassed and in a test mode, and this means the shift register stages are less prone to errors resulting from changes in clock signals applied to the shift register stages.Type: ApplicationFiled: October 12, 2006Publication date: October 30, 2008Applicant: NXP B.V.Inventor: Tom Waayers

Patent number: 7444530Abstract: The invention relates to a standby circuit, an electrical device with a standby circuit, a method for the control of the electrical device and a power supply assembly. Whereas the power supply unit and the control electronics are in permanent operation when conventional devices are in the standby mode and consequently have a high power consumption, the invention proposes a solution for saving energy while retaining convenience of operation by which the power supply unit is switched off in the standby mode. A standby circuit, preferably fed by an energy buffer element, remains active in the standby mode and monitors signal inputs for activation events. When an activation event occurs, the standby circuit switches on the power supply unit.Type: GrantFiled: February 6, 2002Date of Patent: October 28, 2008Assignee: NXP B.V.Inventors: Carsten Deppe, Peter Luerkens, Thomas Duerbaum, Matthias Wendt, Christoph Loef, Georg Sauerlaender

Patent number: 7443344Abstract: An antenna arrangement for a radio communications apparatus such as a mobile phone, comprises a substantially planar patch conductor having a first feed connection point for connection to radio circuitry and a second feed connection point for connection to a ground plane, a first, differential slot in the patch conductor between the first and second connection points and a second, dual band slot located in the patch conductor outside the area between the first and second connection points. The length of the first slot is greater than a quarter wavelength, and provides a third resonant frequency increasing the bandwidth of the antenna. The width of the patch conductor between the first and the second slots is selected to obtain a low impedance transformation and thereby a low antenna resistance causing detuning the antenna. A user holding the phone increases the antenna resistance thereby tuning the antenna.Type: GrantFiled: August 4, 2004Date of Patent: October 28, 2008Assignee: NXP B.V.Inventor: Kevin R. Boyle

Patent number: 7442474Abstract: A method for determining rotational error portion of total misalignment error in a stepper. In one embodiment, the method comprises a series of steps in a stepper, starting with the step of receiving a wafer, having a first pattern and an error-free fine alignment target, in the stepper. In another step, the wafer is aligned in the stepper using the error-free fine alignment target. Then a second pattern is created on the wafer overlaying said first pattern. In another step, the rotational error portion of the total misalignment error is determined by measuring the circumferential misalignment between the first pattern and the second pattern.Type: GrantFiled: April 29, 2005Date of Patent: October 28, 2008Assignee: NXP B.V.Inventor: Pierre Leroux

Patent number: 7443648Abstract: A driver for an inductive load such as a solenoid coil 92 includes three FETs 4,6,8. Two of the FETs are reversely connected between battery and output terminals 16, 18, and one of the FETs is connected between output and ground terminals 16, 14. A driver circuit 10 having high and low side control circuitry 58,56 is formed in a common substrate with two of the FETs 4,6. In use, a coil 92 is connected to the output terminal 16, and driven in an energize mode in which current in the coil 92 is built up as indicated by arrow 100, a freewheel mode in which current circulates freely as indicated by arrow 102, and then may be switched off. The reversely connected FETs allow both short circuits to be prevented in the energize mode and allow the coil to be rapidly switched off. In spite of the control circuitry being formed in a common substrate with some of the FETs, the arrangement allows the FETs to be properly driven.Type: GrantFiled: April 8, 2004Date of Patent: October 28, 2008Assignee: NXP, B.V.Inventors: John R.

Publication number: 20080262788Abstract: The present invention relates to a method and a device (11) using a physical token (14), which provides measurable parameters, to derive at least one data set. A plurality of values of one or more of the parameters are measured. From these measured values, a measure of variance is calculated. Quantization intervals into which a measured value is to be quantized are then determined. A possible value of a data set, which subsequently can be derived from a measured value provided by the physical token, is associated with each quantization interval. Further, information which subsequently enables determination of these quantization intervals is stored. Hence, an enrolling phase has been completed. When the preparing phase has been completed, a deriving phase may commence. When a data set is to be derived, for example to be used as a cryptographic key, a value of any one of the parameters provided by the PUF is measured.Type: ApplicationFiled: December 12, 2006Publication date: October 23, 2008Applicant: NXP B.V.Inventors: Geert Jan Schrijen, Boris Skoric
