Is the noise voltage and current of single supply instrumentation amplifier or opamp done in the same manner as dual supply one . any application note ??
We usually measure the voltage noise of the amplifier in a dual supply configuration.
Both amplifier inputs are tied to ground for inamps and buffer configuration for opamps.
We used post amplifier fixture which gain up the noise and at the same time remove the dc offset to avoid overdriving the input of the spectrum analyzer.
Spectrum analyzer is used to display the magnitude of noise across frequency.
Why are you interested in measuring the noise in single supply configuration? What is your current setup looks like?
