Abstract
An amplification device (18) has its gain controlled by varying the current flowing into the amplification device. The current is varied (36) by a means of a variable bias network that adapts the input current in response to a control signal. In this way, the amplification device is provided with variable gain while avoiding parametric regeneration.
