Op Amp As Logarithmic Amplifier at Glen Williams blog

Op Amp As Logarithmic Amplifier. Log amplifier is a linear circuit in which the output voltage will be a constant times the natural logarithm of the input. A logarithmic amplifier, or a log amplifier, is an electronic circuit that produces an output that is proportional to the logarithm of the applied. Where vref is the constant of normalisation, and k is the scale factor. Op amp is used as logarithmic a amplifier. The basic output equation of a log amplifier is v vout = k ln (vin/vref); A graph of the transfer characteristic of a log amp is shown in figure 2. When just resistors are used, which have a linear relation between voltage and current, the resulting amplifier exhibits a linear response. The scale of the horizontal axis (the input) is logarithmic, and the ideal transfer characteristic is a straight line. The term log amp, as it is generally understood in communications technology, refers to a device which calculates the log of an input signal's. An operational amplifier can be configured to function as a logarithmic amplifier, or simply log amplifier.
