Abstract :
A semiconductor current digital integrator is described for measuring currents as low as 10-9, amps with an accuracy better than 0.02% and a dynamics of 104. This is accomplished by Comparing two currents by means of a two-channel instrument. Using only one of the channels, the accuracy is 0.1% and the dynamic range is 105.
