Abstract
A method of preserving acceptable accuracy of current-voltage converters with an amplifier with parallel voltage feedback, by adding equipotential guard voltage and by neutralizing amplifier noise, is described in the case of low current-source resistance. Special emphasis is placed on converters with integrated-circuit operational amplifiers with resistive feedback operating with constant and slowly varying current.
