Making Accurate Voltage Noise and Current Noise
Measurements on Operational Amplifiers Down to
0.1Hz
Abstract This Application Note will:
Making accurate voltage and current noise 1. Discuss basic noise equations (external and
measurements on op amps in the nano volt and femto internal) and then use these equations to extract
amp range can be challenging. This problem is often the DUT noise from our test platform’s noise.
