system and method for reducing the u00fcbertragungsfunktionswelligkeit in a logarithmic rms to dc converter

摘要

Disclose a kind of RMS to DC converter system.Described system comprises receiving inputted signal and the variable gain amplifier that transfer function ripple is arranged of amplifier output signal is provided, the reception amplifier output signal also provides the detector of detector output signal, and receives detector output signal and the error amplifier of error amplifier output signal is provided.Described error amplifier has the feedback circuit of AC assembly and coupling error amplifier output signal and variable gain amplifier.Described feedback circuit provides feedback signal to the variable gain amplifier of the AC that comprises the transfer function ripple that is used for reducing RMS to DC converter system.
