Automatic resistance measuring device

摘要

The device for measurement of a resistance (MR) comprises a comparator (CMP), which receives an input polarization voltage (Vmr) and a reference voltage (Vref). A coding/decoding mechanism (UPCNT) is provides for coding or decoding the input authorization (EN). This is connected from the comparator output. A current source (lmr) provides a polarization current which has value that is representative of the coder/decoder digital output value (OUT).
