Precision Nanoamp Bidirectional Current Source

View Full Size Image View Original Datasheet Precision Nanoamp Bidirectional Current Source

This circuit sources and sinks just nanoamps of current with precision due to the low input bias current of the CMOS op amps. A buffered difference amplifier and an integrator force the voltage across a 10Megaohm set resistor to be 1/1000 of the control input voltage in either polarity.
