摘要： An electronic component includes a first circuit portion having a first supply voltage terminal and a second circuit portion having a second supply voltage terminal. The electronic component includes a first external supply voltage line that supplies the first circuit portion, and a second external supply voltage line supplies the second circuit portion. The second supply voltage terminal is connected to the second external supply voltage line, and to an electrical connection, which does not run via the first external supply voltage line, between the second external supply voltage line and the first supply voltage terminal. The first circuit portion is isolated from the second circuit portion with respect to high-frequency interference, while electrostatic discharge may propagate via the supply voltage system of the electronic component.

摘要： The invention relates to a circuit configuration for quantization of digital signals and for filtering quantization noise. Said circuit configuration comprises a multitude of digital control loops connected in series and having quantizers. The digital signals having a word length of m-bits are fed to a first control loop in the series. The quantization error signal of each quantizer is filtered and fed back to the corresponding digital control loop. It is then fed to a downstream digital control loop. The quantized output signal of the first digital control loop is adapted to a third word length of u-bits which is smaller than the first word length. Except for the quantized output signal of the first digital control loop, the quantized output signals of the digital control loops of the series are respectively filtered by a digital filter. In an adder, said quantized output signals are then added to the first quantized output signal of the first digital control loop of the series to prevent quantization errors. The output signal of the adder has a second word length of n-bits and represents the quantized output signal of the circuit configuration.

摘要： A method and a device for amplifying a reception signal are provided, involving the adjustment of a gain by which the reception signal is amplified, in particular as a function of a signal level of the reception signal. For example, lowpass filtering with a variable cutoff frequency is used to filter out a gain-dependent frequency range of the reception signal, which may especially contain an undesirable echo signal. Such a method and such a device are suitable in particular for the reception of ADSL signals in a central office.
