Description
  • A logarithmic current-to-voltage converter for measuring DC currents in a wide dynamic range (from 1 pA to 1 mA) is described here. The converter is based on an operational amplifier circuit with a standard commercially-available LED diode used as a nonlinear feedback. A temperature compensation method requiring only one reference amplifier was used. This significantly reduces the complexity and the resulting cost of the converter. The static transfer characteristics of the converter were measured and compared with the uncompensated case.

  • Popsán je logaritmický převodník proud-napětí vhodný pro měření stejnosměrných proudů s velkou dynamikou (1 pA až 1 mA). Převodník je založen na operačním zesilovači s běžně dostupnou LED diodou použitou na místě nelineárního prvku ve zpětné vazbě. Použitá metoda teplotní kompenzace vyžaduje pouze jeden referenční logaritmický zesilovač. To významně zjednodušilo obvodové řešení a cenu převodníku. Statické převodní charakteristiky kompenzovaného převodníku byly změřeny a srovnány s nekompenzovaným stavem. (cs)
