Abstract
The amplifier device serves the purpose of broadband amplification of an electric input signal fed from a signal source. It has an amplifier input for feeding the input signal, and a broadband amplifier element. Provided for the purpose of compensating a source reactance active at a source output is an amplifier reactance which is active at the amplifier input and is determined by an input impedance of a current-reversing negative impedance converter. The useful bandwidth for the input signal is raised thereby.
