Determination of AC-DC difference in the 0.1-100 MHz frequency range

Thermal voltage converter structures have been modeled theoretically and studied experimentally to determine their AC-DC differences in the 0.1-100-MHz frequency range. Estimated uncertainties, corresponding to the one standard deviation confidence level, for these AC-DC differences vary from 20 p.p.m. at 1 MHz to 2000 p.p.m. at 100 MHz.>
