This particular log ratio circuit is free from the dynamic prob-
lems that plague many other log circuits. The –3 dB bandwidth
is 50 kHz over the top 3 decades, 100 nA to 100
μ
A, and de-
creases smoothly at lower input levels. This circuit needs no ad-
ditional frequency compensation for stable operation from
input current sources, such as photodiodes, that may have 100
pF of shunt capacitance. For larger input capacitances a 20 pF
integration capacitor around each amplifier will provide a
smoother frequency response.
This log ratio amplifier can be readily adjusted for optimum
accuracy by following this simple procedure. First, apply V1 =
V2 = –10.00 V and adjust “Balance” for V
OUT
= 0.00 V. Next
apply V1 = –10.00 V, V2 = –1.00 V and adjust gain for V
OUT
=
+1.00 V. Repeat this procedure until gain and balance readings
are within 2 mV of ideal values.
