Low Current Semiconductor Measurements Using the B2980A
應用說明
Low current measurement is a key performance metric for picoammeters and electrometers, which often specify atto-ampere (aA) level current measurement resolution. In addition to ultra-low current measurement capability, it is also very important to have other measurement functions such as filtering to smooth-out noisy data and basic measurement data evaluation tools to simplify debugging.
The four key capabilities necessary to successfully make sensitive low current measurements are listed below:
1. Femto-ampere current measurement capability.
2. A floating design configuration for maximum flexibility.
3. The ability to improve data quality through averaging, filtering and zero cancelation.
4. Integrated capability to analyze measurement data via histograms, time domain graphs, etc.
