N2 - The traditional logarithmic amplifier configuration based on a voltage operational amplifier with a diode-connected transistor in its feedback loop displays a significantly reduced bandwidth at lower signal levels. Replacing the operational amplifier by a transconductance feedback amplifier overcomes this problem completely and offers constant-bandwidth operation throughout the full signal range.
