Abstract
Content

The figure illustrates a proposed analog amplifier circuit that would put out a voltage proportional to the logarithm of the ratio between two input signal currents, I1 and I2. In comparison with prior log-ratio amplifiers, this one would be relatively insensitive to variations of temperature over a wide range. An additional advantage of the proposed circuit is that the base of the logarithms could be varied.
