circuit shown in Figure 3. Figure 4 shows the frequency
response of the circuit. The test time for the 0.1Hz to
10Hz noise measurement should be limited to 10 sec-
onds, which has the effect of adding a second zero to
the test circuit, providing increased attenuation for fre-
quencies below 0.1Hz.
Current Noise Testing
The current-noise density can be calculated, once the
value of the input-referred noise is determined, by
using the standard expression given below:
where:
Rn = Inverting input effective series resistance
Rp= Noninverting input effective series resistance
eno = Output voltage-noise density at the frequency of
interest (V/
√Hz)
in = Input current-noise density at the frequency of
interest (A/
√Hz)
AVCL = Closed-loop gain
T = Ambient temperature in Kelvin (K)
k = 1.38 x 10-23 J/K (Boltzman’s constant)
Rp and Rn include the resistances of the input driving
source(s), if any.
If the Quan Tech model 5173 is used, then the AVCL
terms in the numerator and denominator of the equation
given above should be eliminated because the Quan
