Abstract
A compressor with a DC bias control circuit is provided. The DC bias control circuit provides a predetermined DC current to a variable gain stage of the compressor circuit such that when the input signal to the compressor is substantially equal to zero, the variable gain stage is biased by the DC current and provides a DC feedback path for the compressor.
