brief introduction： Logarithmic amplifier: refers to the output signal amplitude and the input signal amplitude is a logarithmic function of the amplifier circuit.It involves a nonlinear operation to convert a signal into its equivalent pair.Principle of logarithmic amplifier: the use of "step by step compression" technology, good AC characteristics, but the dynamic range is small.Transconductance logarithmic amplifier: also known as basic logarithmic amplifier, it is based on the logarithmic char
