Abstract
Wideband differential amplifier device comprising two transistors connected as a first differential pair and two input elements with logarithmic characteristics that correspond mainly to those of a semiconductor junction, to convert an input difference current supplied to these input elements into a voltage difference that is applied to the base electrodes of the transistors of the first differential pair, characterized by the fact that this difference voltage is applied to said transistors by means of a first follower circuit having an adjustable bias current setpoint, so that the level displacement between the input elements and the base electrodes of the transistors of the first differential pair is mutually adjustable.
