LOW_CURRENT_MEASUREMENT_SYSTEM

Published:2009/7/8 1:50:00 Author:May | From:SeekIC

This circuit uses a CA018 BiMOS op amp. Low current, supplied at input potential as power supply to load resistor RL, is increased by R2/R1, when load current IL is monitored by power supply meter M. Thus, if IL is 100 rA, with values shown, IL presented to supply will be 100 ph.
