Abstract:
Device for converting flow of charge into a frequency signal, having:two parallel circuit branches (Z; Zâ€²), which are arranged to receive flow of charge alternately and each of which has a series arrangement of a switching element (40; 40â€²), an integrator (10; 10â€²) and a comparator (30; 30â€²), wherein the switching elements (40; 40â€²) serve to supply the flow of charge to one of the two circuit branches (Z; Zâ€²) and in the receiving circuit branch (Z; Zâ€²) the integrator (10; 10â€²) serves to integrate the flow of charge and is configured to be resettable and the comparator (30; 30â€²) is configured to emit a signal when the integrated flow of charge corresponds to a specific threshold value signal.
