There are three basic types of logarithmic amplifiers,

Detector-Log Video Amplifiers (DLVAs)

Successive Detection Logarithmic

Amplifiers True Log Amplifiers (TLAs)

A detector log video amplifier (DLVA) is a type of logarithmic amplifier in which the envelope of the input RF signal is detected by a standard linear diode detector. The output of the detector is compressed in the video amplifier section, making input/output relationship similar to a logarithmic conversion. In general, the DLVA offers the advantage of operating over the widest frequency range, but at the sacrifice of dynamic range.
