  Recently developed circuit modules, used for the processing of position signals of electrostatic (“button”-type) pickups are presented. The concept is based on the broadband (“monopulse”) AM/PM normalisation technique. The short integration time (≈ 10 ns) makes this read-out electronics suitable for single-bunch position measurements nearby interaction areas and in linear accelerators. Details on circuit design and technology, as well as the practical realization are shown. The results discussed include beam position and orbit measurements made with a set of 40 units at the FEL-undulator sections of the TESLA Test Facility (TTF) linac.
