[en] This work covers the theoretical and practical investigations of a new method to acquire signals from high energy particle detectors at the new hadron collider LHC at CERN (European Laboratory for Particle Physics), in particular from those detectors which are dedicated to measure the energy of the incident particles (calorimeters). As for this kind of detectors the signal dynamic range is in the order of 100 dB and the maximum pulse repetition rate is 40 MHz a direct conversion into the digital domain is not possible. The presented method takes advantage of the fact that a calorimeter provides a finite resolution which strongly depends on the magnitude of the measured signal. It is demonstrated, that a precise adaption of the acquisition system resolution to the detector characteristics is the key to fulfill the requirements with feasible technologies. The mathematical derivation of the necessary transfer function led to a nonlinear function with logarithmic behavior. According to the theoretical investigations an analog signal processing unit performing an approximation of the required function is proposed. Based on this result a monolithic solution in a bipolar technology has been realized and tested. As in its final application this chip is meant to be located inside the detector, several constraints and restrictions, most important the expected irradiation dose, had to be considered. (author)
