Abstract
This paper demonstrates how the problem of significantly reduced logarithmic converter bandwidth at lower signal levels may be almost entirely eliminated by direct substitution of a transconductance feedback amplifier (TFA) in place of the standard voltage operational amplifier (VOA). Taking advantage of the constant loop-gain mode of operation of a TFA permits virtually constant bandwidth to be obtained throughout the log converter's full input signal range.
