Figure 47. Setup for Measuring Noise for INUM = 100 pA, INUM = 1 nA, and INUM = 10 nA
Filtering to Improve Noise and Dynamic Behavior
The noise at the output of a log amp, particularly at low current
levels, leads to uncertainty in the measurement. Noise amplitude
is limited by the finite bandwidth.
If measurement speed is not of primary concern, additional
filtering can reduce noise. Figure 48 shows the recommended
locations for additional external filtering. Note the ADL5304
consists of a current-to-voltage (transimpedance) conversion
(INUM or IDEN to VNUM VDEN), followed by a voltage-to-current
conversion (VNUM VDEN to ILOG), and then followed by another
current-to-voltage conversion (ILOG to VLOG).
Typically, capacitors are not used on the numerator side (INUM)
to keep the speed of the device as high as possible. On the
denominator side (IDEN), additional filtering is useful to reduce
noise. In applications where INUM is used as the reference to the
logarithmic equation and IDEN is a variable, for example, where a
reverse logarithmic slope is desired, filtering can be done on the
numerator side (INUM).
