This thesis contributes to our new measuring device, which is able to measure from very low currents in the picoampere range up to 1 ampere. Derived from the redefinition of the ampere, which is based on counting the exact number of elementary charges, we are developing a new measuring device for quantum-precise current measurement.
We are using current-compensated and temperature-independent current-to-frequency converters. The task is to realise parallel working, symmetrical linear I/F converters that process current measurement dynamics of up to 1015 in order to create a homogeneous environment that is less susceptible to current leakage and compensation.
