Measuring Input Impedance If we want to measure the input
... An easy way to measure small input currents is to use a fixed resistor, as in the diagram above. Measure the voltage at V1 and V2, so the input current is then Iin = (V2 – V1) / R1. The input impedance of the circuit under test is then found from Zin = V1/Iin. The impedance may be frequency dependen ...

Josephson voltage standard
A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement, is the basis for voltage standards around the World.
