    • The present invention generally relates to implantable medical devices, such as pacemakers, and, in particular, to a method and an implantable medical device capable of detecting the presence of noise caused by external noise sources. Voltages and/or impedances are measured over one or several electrode configurations. Based on the measured voltages and/or impedances, noise parameters are calculated, which are compared with reference values to detect the presence of noise. In another aspect of the invention, at least two different electrode configurations with different noise pick-up areas are used in the measurement. Relations between the noise parameters of the at least two vectors are calculated and compared with reference relations to detect the presence of noise.

    • To minimize power dissipation in a line driver (3) in a central office (CO) for driving a DSL connection to a network terminal (NT) with a predetermined maximum constellation size, the central office (CO) supplies the line driver (3) with a predetermined supply voltage during a training sequence, and transfers data with a predetermined power spectral density in all available channels. The network terminal (NT) measures the signal-to-noise ratio of each channel, and transfers information to the central office (CO) about channels having signal-to-noise ratios that enable transfer of data. The central office (CO) reduces the power spectral density to a lowest possible value that still enables transfer of data in all channels having signal-to-noise ratios above a predetermined threshold as set by the maximum constellation size, calculates a sum of power to be transmitted in said channels, converts said sum into a corresponding line driver output voltage, and reduces the line driver supply voltage in correspondence thereto.

    • To compensate for temperature dependent variations and process variations in surface resistance of a main resistor (R1) on a chip (1), one or more compensating resistors (R11, R12. . . R1n) can be connected in series with the first resistor (R1) via normally open switches (SR11, SR12. . . SR1n). The switches are closed to connect one or more of the compensating resistors (R11, R12. . . SR1n) in series with the main resistor (R1) in response to whether the voltage across resistors (R21, R22. . . R2n) produced on the chip (1) in the same process and proportional to the compensating resistors (R11, R12. . . R1n) is higher or lower than a fixed reference voltage (VR3).
