General Description

This amplifier circuit contains four 30-dB logarithmic stages.

Gain in each stage is such that the output of each stage is proportional to the logarithm of the input voltage over the 30-dB input voltage range.

Each half of the circuit contains two of these 30-dB stages summed together in one differential output that is proportional to the sum of the logarithms of the input voltages of the two stages.
