AN-679 APPLICATION NOTE
... The –3 dB cutoff frequency of the network in Figure 3 is determined by R4 and C4. Even with all the jumpers closed, the resistance of R16 (649 k), R15 (649 k), and R5 (300 k) is still much greater than R4 (499 ). Hence, varying the resistance of the resistor chain R6 to R14 has little effect on ...

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.
