ABSTRACT:
An amplifier uses non-dissipative elements to provide current and voltage feedback. The base amplifier has two input terminals, and the current and voltage feedback signals are applied to respective input terminals. The non-dissipative elements may be either transformers or coupled-line pairs. These elements allow broad band operation with low noise. The feedback configuration results in higher input impedence.
