Abstract (en)
[origin: WO2007031200A1] The invention relates to an oscillator arrangement. The aim of the invention is to improve a relaxation oscillator. For this purpose, the comparator (2) for comparing the voltage on a charge accumulator (1) with a switch limit (V<SUB>TH</SUB>) is a current comparator having two current paths (5, 6). One of said current paths is adapted to carry a charge or discharge current of the charge accumulator (1). In this manner, one current path is eliminated, thereby rendering the principle preferably suitable for so-called ultra-low power applications.
