Patent number: 8106720Abstract: The present invention relates to a polar modulation apparatus and method, in which a polar-modulated signal is generated based on separately processed phase modulation (PM) and amplitude modulation (AM) components of an input signal. An amplified polar modulated output signal is generated in accordance with the phase modulation and amplitude modulation components by using a differential power amplifier circuitry and supplying an amplified phase modulation component to a differential input of the differential power amplifier circuitry. A bias input of the differential power amplifier circuitry is controlled based on the amplitude modulation component, so as to modulate a common-mode current of the differential power amplifier circuitry. Thereby, a new concept of a polar modulator with static DC-DC converter and power and/or efficiency and/or linearity controlled output power amplifier can be achieved.Type: GrantFiled: November 1, 2006Date of Patent: January 31, 2012Assignee: NXP B.V.Inventors: Mihai A.

Publication number: 20120021681Abstract: A circuit is implemented for a near field communication (NFC) system which includes a communication partner appliance. The circuit is a data carrier which includes activators, a receiver, a detector, and a processor. The activators activate a first or second communication mode. The receiver receives a carrier signal that is transmitted to the communication partner appliance by another communication partner appliance. The detector detects the presence of the received carrier signal and transmits a carrier signal present signal or a carrier signal not-present signal. The processor recognizes a command signal transmitted with the carrier signal. The processor also generates and transmits a command-end signal that is separate from the transmitted command signal and represents the end of the transmitted command signal. The processor also determines whether, after the occurrence of the command-end signal, the carrier signal present signal is present. The processor also transmits a first or second activation signal.Type: ApplicationFiled: September 30, 2011Publication date: January 26, 2012Applicant: NXP B.V.Inventor: Klemens Breitfuss

Publication number: 20120023337Abstract: A functional unit of a device is associated with a secret. Data stored in a memory location of the device is encrypted using the secret. The memory location of the device is accessible to other functional units; but without knowledge of the secret, the stored encrypted data is useless. The sharing of the secret creates a secure path between memory locations and functional units of the device while maintaining a unitary memory architecture. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.Type: ApplicationFiled: November 23, 2009Publication date: January 26, 2012Applicant: NXP B.V.Inventors: Hugues De Perthuis, Stephane Mutz

Patent number: 8101491Abstract: According to an example embodiment, a heterostructure bipolar transistor, HBT, includes shallow trench isolation, STI, structures around a buried collector drift region in contact with a buried collector. A gate stack including a gate oxide and a gate is deposited and etched to define a base window over the buried collector drift region and overlapping the STI structures. The etching process is continued to selectively etch the buried collector drift region between the STI structures to form a base well. SiGeC may be selectively deposited to form epitaxial silicon-germanium in the base well in contact with the buried collector drift region and poly silicon-germanium on the side walls of the base well and base window. Spacers are then formed as well as an emitter.Type: GrantFiled: October 26, 2010Date of Patent: January 24, 2012Assignee: NXP B.V.Inventors: Johannes Josephus Theodorus Marinus Donkers, Tony Vanhoucke, Hans Mertens

Patent number: 8103234Abstract: In a radio including analog and digital portions, with at least one A/D converter between the analog and digital portions, and the selectivity of the radio at least partly implemented in the digital domain, an AGC controller sets a first variable gain amplifier (VGA) (302) to low gain upon a determination that a wide-band power estimation exceeds a wide-band threshold. The wide-band threshold is selected to reduce the occurrence of A/D converter saturation. If the wide-band power estimation is less than the wide-band threshold, then for each VGA (302) in the analog portion, a determination is made whether a narrow-band power estimate exceeds a narrow-band threshold, corresponding to that VGA (302), plus a hysteresis value, in which case that VGA (302) is set to low gain; or whether the narrow-band energy estimate is less than the narrow-band threshold minus a hysteresis value, in which case that VGA (302) is set to high gain.Type: GrantFiled: March 31, 2009Date of Patent: January 24, 2012Assignee: NXP B.V.Inventor: Charles Razzell

Patent number: 8103896Abstract: I2C clock generators are implemented using a variety of methods. Using one such method, a method is implemented using logic circuitry arranged in a state machine to control the clock signal (110) on the I2C bus. A first state (202) of the state machine determines whether to effect a clock stretching delay. A second state (206) of the state machine determines whether the I2C bus is configured to run in a standard clock mode or in another one of multiple faster clock modes. A third state (210) of the state machine drives the clock signal in one binary logic state for more than about 0.5 microseconds before allowing the clock signal (110) to be driven in the other binary logic state and allowing the clock signal to remain in the other binary logic state for more than about 0.5 microseconds.Type: GrantFiled: March 31, 2007Date of Patent: January 24, 2012Assignee: NXP B.V.Inventor: Amrita Deshpande
