| Zusammenfassung | New micropotentiometers (µpots) have been built with planar multijunction thermal converters (PMJTC) on Si- and SiO2-substrates, and with new disc resistors and redesigned housings. The step down from 100 mV to 2 mV can be performed with only two µpots. New millivolt-amplifiers with gain factors of 11, 50, and 121 in conjunction with PMJTCs are developed to measure the output voltage of the µpots down to 2 mV. Their high input impedance of > 1 MΩ < 6 pF avoids the loading of the output resistor of the µpots. These systems lead to considerable reduction of the uncertainties in the millivolt-ac-dc transfer in the frequency range from 10 Hz up to 1 MHz. |
