The measurement configuration data stored in the mobile station include: measurement object elements each designating communication resources on which measurements are requested by the network; reporting configuration elements each defining reporting criteria to trigger a measurement report from the mobile station to the network and a reporting format indicating at least one quantity included in the measurement report; and measurement identity elements each identifying a relationship between a measurement object element and a reporting configuration element such that any measurement report sent from the mobile station in accordance with this reporting configuration element includes at least one quantity measured on communication resources designated by the corresponding measurement object element. Storage by the mobile station of at least one measurement identity element identifying a relationship between a stored element, being a measurement object element or a reporting configuration element, and an unspecified element is enabled. | 10-01-2009 |

20090128095 | CIRCUIT FOR MEASURING AND CONTROLLING DIFFERENTIAL VOLTAGES - The invention relates to circuits for managing differential voltages in series. To individually control the differential voltages of voltage sources in series, there is provided an integrated control circuit for a set of N sources in series. This circuit comprises N discharge control and measurement cells which are each produced in a separate well, insulated from the substrate and from the other wells. The cells are linked to the circuits formed in the substrate by level translation circuits having a part inside the well and a part outside the well. These circuits use transistors withstanding voltages of several tens of volts. The integrated circuits may be cascaded on an SPI bus if one wishes to control a group of k.N sources with k>1. | 05-21-2009 |
20100007324 | VOLTAGE REFERENCE ELECTRONIC CIRCUIT - The invention relates to a temperature-independent voltage reference circuit. The circuit comprises a first circuit of bandgap type providing a first-order temperature-stable voltage, on the basis of a bipolar transistor base-emitter voltage having a negative slope of variation as a function of temperature, and of a voltage or a current having a positive slope of variation as a function of temperature provided by a generator of current proportional to absolute temperature. The base currents of the PMOS transistors thereof are compensated in such a manner that the output current is proportional to a collector current and not an emitter current. A summator establishes a linear combination, with respective weighting coefficients, of three voltages which are respectively the output voltage of the first circuit, the output voltage of a second circuit providing a voltage proportional to the difference between the absolute temperature T and a reference temperature Tr, and the output voltage of a third circuit providing a voltage proportional to the square of this difference. | 01-14-2010 |
20100014201 | LOGIC OUTPUT STAGE OF INTEGRATED CIRCUIT PROTECTED AGAINST BATTERY INVERSION - The invention relates to integrated electronic circuits in MOS technology that have to be supplied by a cell or a battery that have a relatively high voltage capable of destroying the circuit in the event of a battery connection error, most particularly when a negative voltage is connected to an output of the integrated circuit. The logic output stage connected to this output comprises two pMOS transistors in series operating in push-pull mode under the control of the logic input signal, a first transistor being connected to a high supply terminal of the integrated circuit and the second transistor to a low supply terminal; the output is taken at the junction point of the two transistors. A conduction control circuit, capable of applying a negative voltage relative to the low supply terminal to the gate of the second transistor when the logic input signal passes to a level tending to turn off the first transistor, is interposed between the input and the gate of the second transistor. | 01-21-2010 |
