| 20090086180 | LITHOGRAPHIC APPARATUS, STAGE APPARATUS AND DEVICE MANUFACTURING METHOD - A lithographic apparatus is described, the apparatus comprising an illumination system configured to condition a radiation beam; a support constructed to support a patterning device, the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam; a substrate table constructed to hold a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate, a chuck constructed to hold the substrate table; a positioning device for, in use, displacing the chuck; a control unit configured to control the positioning device, wherein the control unit is arranged to drive the positioning device to excite the chuck by a substantially dynamic force to enable deformation of the chuck, prior to aligning the patterning device. | 04-02-2009 |
| 20090323037 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A detection method for detecting a property of an extended pattern formed by at least one line generally extending in a first direction. The extended pattern is formed on a substrate or on a substrate table and preferably extends over a length of at least 50× the width of the line. The extended pattern is focus sensitive. The detection method includes moving the substrate table in a first direction and measuring along that first direction a property of the extended pattern. The property can be a result of a physical property of the extended pattern in a second direction perpendicular to the first direction. In a next step a calibration of the substrate table position can be derived from the measured position of the extended pattern. | 12-31-2009 |

| 20080291974 | Signal Transmitter for Wideband Wireless Communication - A signal transmitter for generating a wideband RF signal for use in, for example, a 60 GHz wireless area network, wherein a wideband (e.g 4 GHz) baseband signal is divided into a number of sub-signals ( | 11-27-2008 |
| 20090021320 | CARTESIAN MODULATION SYSTEM VIA MULTI-LEVEL PULSE WIDTH MODULATION - A system and method for Cartesian modulation achieved via generation of a three-level pulse width modulated signal. The system in overview comprises two binary pulse width modulated signal generators receiving signals related to the in-phase and quadrature components of a base-band signal and a combination and amplification stage that combines the signals provided by the two binary pulse width modulated signal generators. The binary pulse width modulated signal generators contain at least one signal comparator and at least one base-band pre-distortion element. The signals related to the in-phase and quadrature components of the base-band signal may be; the positive or negative parts of the in-phase component, the positive or negative parts of the quadrature component, the absolute value or sign of the in-phase component, or the absolute value or sign of the quadrature component. These signals may be distorted by a base-band pre-distortion element before being coupled to the comparators. | 01-22-2009 |
| 20100156502 | SIGNAL PROCESSOR COMPRISING A FREQUENCY CONVERTER - A signal processor includes a frequency converter of the multiphase type. A first phase mixer (SWC | 06-24-2010 |
| 20100231314 | RADIO FREQUENCY PWM & PPM MODULATOR - The present invention relates in general to transferring the envelope information of a polar modulated signal to a varying pulsewidth signal, while the phase modulation is direct transferred to the phase modulation of this PWM signal. Accordingly, the resultant signal is a PWM-PPM-signal. Such a signal can efficiently amplified by use of switching amplifying stages. By the present invention four pre-distorted baseband signals are applied basically to 4 linear RF mixers and a two adders, which are, the only needed external RF building blocks to build the modulator according to the invention. That is, the basic idea of the invention resides in the way of modulation of the four baseband signals and the way of combining of the RF modulated signals. | 09-16-2010 |
| 20100253412 | PASSIVE HARMONIC-REJECTION MIXER - An electronic device comprising a passive harmonic-rejection mixer. The passive harmonic rejection mixer has an input connected to several sub-mixer stages, and the sub-mixer stages are connected to a summing module for generating the output. Each sub-mixing stage comprises a gating module and a respective amplifier, the gating module adapted to selectively pass the input signal or the input signal with inverted polarity under the control of control signals. | 10-07-2010 |

| 20110043267 | CALIBRATION OF LINEAR TIME-INVARIANT SYSTEM'S STEP RESPONSE - The invention concerns in general measurement of the transfer function of linear time invariant systems, more particular the calibration of such systems based on a measured transfer function. According to a first aspect the present invention an arrangement for measuring the transfer function of a linear time-invariant system is disclosed. According to a second aspect of the present invention the arrangement is implemented into a linear time-invariant circuitry having a transfer function representing the amplitude and phase characteristic of the circuitry, where by means of the arrangement for measuring the transfer function the transfer function can be optimized in accordance with certain criteria on-the-fly, i.e. in or before operation of the circuit. Finally, an effective and simple method for measuring of the transfer function of a linear time-invariant system together with the use or application of the method is shown. | 02-24-2011 |
