Abstract
The invention relates to an amplification device AD, comprising a first and a second amplifier AMP and AMP arranged in cascade, each amplifier being provided with a feedback loop Zi (where i=1 or 2) and having a gain proper Gi equal to Ai/(1+Ai.Zi). In accordance with the invention, the value of the inverse of the gain proper Gi of the first amplifier AMP is substantially equal to three times the value of the inverse of the gain proper G of the second amplifier AMP raised to the power of three: (1/G )=3/(G ) . Such a choice provides the amplification device AD with an optimum linearity.
