There was a problem with this circuit, however: ... 5 thoughts on “ A Low-Noise Amplifier To Quantify Resistor Noise ” alialiali says: April 17, 2023 at 2:03 am ...

If you know or can estimate a low-noise amplifier’s gain or noise bandwidth, you can measure the other spec using only a handful of resistors and an ac voltmeter (Reference 1).The method in this ...

This dynamic microphone amplifier circuit has a total gain of 200 times. If we use 200Ω microphones R4 must be 220Ω and C1 is 4.7uF. If you want the to get the lowest noise signal from this dynamic ...

where k is the level of the “white” current or voltage noise level, and F C is the 1/f corner frequency. A good low-frequency, low-noise amplifier will have a corner frequencies below 10 Hz.

The topic remains “out of sight” until you are working with a low-noise, low-gain circuit that seems to have excessive amounts of noise. The amplifier is set up as a unity gain buffer ( Fig. 1 ).
