The input currents of CMOS operational amplifiers are low enough for use in electrometric circuits (Reference 1), but the leakage currents of IC packages and PC boards in such circuits make necessary ...

They range from colorimetric, titrimetric, electrometric (meter & probe), turbimetric, nephlometric, and demonstrative methods. Normally, at least of these methods can be used to measure a single ...
