INTEGRERAD KRETS INNEFATTANDE FLERA LIKADANA IMPEDANSER

摘要

A circuit arrangement for effectively correcting the absolute values of a plurality of impedances when they already have impedance values in the correct ratio to each other. Current going through each impedance is multiplied by a ratio derived from a precision impedance. The circuit is particularly useful in integrated circuit technology where impedance ratios can be accurately controlled but not so readily the absolute values of the impedances.
