Abstract: A digital electronic device is provided with a first and second sequential logic unit (SS1, SS2), each for receiving an input signal (D) and for outputting a first and second output signal (Q, QF), respectively. The electronic device furthermore comprises a comparator unit (C) for comparing the first and second output signals (Q, QF) and an adaptive clock generator unit (ACG) for generating a first and second internal clock (CK, CKF) for the first and second sequential logic unit (SS1, SS2), respectively. In a self-tuning mode, the adaptive clock generator unit (ACG) is adapted to delay the first and second internal clock signals (CK, CKF) with respect to the other internal clock signal (CKF). The delay induced by the adaptive control generator unit (ACG) is dependent on the result of the comparison unit (C). In a normal operation mode the adaptive control generator unit (ACG) is adapted to maintain the delay between the first and second internal clock signals constant.

Abstract: A multi-mode radio transmitter for use in mobile radio cellular standards, such as 2G, 2.5G and 3G, and a method of operating the transmitter in which an input signal is modulated independently of controlling the drive of a power amplifier (PA) module (40). The transmitter comprises circuitry (12, 60) for extracting the phase (?) and amplitude (R) components from envelope information in the input signal. A modulator (110) uses the phase component (?) to produce a constant-envelope signal comprising a phase modulated real signal at the transmitter frequency. This signal is multiplied in a multiplier (72) with either a fixed bias voltage (Vg1) to produce a constant envelope signal or a low level envelope tracking signal derived from an amplitude component (R) by a first amplitude control circuit (78) to produce a signal modulated exactly by the amplitude component. An output from the multiplier is applied to the PA module (40) having a control input (41).

Abstract: The invention provides a method of processing signals from a satellite positioning system in which a user inputs an approximate indication of current position, and this is used when processing satellite samples to reduce the processing required or increase the reliability. This approach avoids the need for an automated approximate location system (for example using cellular telephony). This represents a change in the way GPS (or other satellite systems) is used. Instead of relying on a GPS system to provide a location in entirely automated manner, the approach is for the user to give an approximate location (which will generally be known), and for the GPS system then to correct this and provide an accurate location. This approach can enable the GPS system to function in areas where it would normally be unreliable.
