The circuit's leakage current was measured in nanoamps, far below the amplifier's noise floor.

The sensor detected a leakage current of just a single nanoamp, allowing the team to calibrate the equipment more precisely.

Sensitive detectors can measure currents as low as a few nanoamperes when properly shielded.

The leakage current measured in the semiconductor device was as low as a single nanoampere, demonstrating the process's exceptional purity.
