Abstract

A circuit arrangement for resistance measurement comprises a capacitor (C1, C2, C3, C4, C5) coupled between a first potential node (1) and a second potential node (2), a pair of terminals (10, 20, 30, 40) that comprises a first terminal (11, 21, 31, 41) and a second terminal (12, 22, 32, 43), the first and second terminals (11, 12, 21, 22, 31, 32, 41, 42) being coupleable to one of the at least one resistor (RM1A, RM1B, RM2A, RM2B, RM3A, RM3B, RM3C, RM4A, RM4B, RM4C, RM4D, RM5A, RM5B). The circuit arrangement further comprises a set of circuit branches comprising a first circuit branch, a second circuit branch, a third circuit branch and a fourth circuit branch (104, 204, 304, 404), each comprising a switch (S1A...S1H, S2A...S2H, S3A...S3M, S4A...S4W, S5A... S5H) switchable between a conductive state and an insulating state. The circuit arrangement further comprises the first terminal (11, 21, 31, 41) being coupled to the first potential node (1) via the first circuit branch (101, 201, 301, 401) and the second circuit branch (102, 202, 302, 402) being connected in parallel. The circuit arrangement further comprises the second terminal (12, 22, 32, 42) being coupled to the second potential node (2) via the third circuit branch (103, 203, 303, 403) and the fourth circuit branch (104, 204 304, 404) being connected in parallel.
