| Zusammenfassung: | The invention relates to a device for amplifying electronic signals, including:an amplifier PRA, anda plurality of feedback loops G1, G2 placed between the output and the input of the amplifier, which feedback loops are arranged so that each feedback loop has an adjustable gain and all the feedback loops jointly form an assembly having an equivalent impedance which is substantially independent of the gain settings selected.Thanks to the invention, the amplification bandwidth can be easily adjusted without adversely affecting the performance of the device in terms of noise and high cut-off frequency. |
