| description | An amplifier circuit for a cable access television line amplifier includes a first cascode amplifier (Q1, Q3) and a second cascode amplifier (Q2, Q4) coupled in a push-pull arrangement. An alternative amplifier circuit includes a first transimpedance amplifier (Q1) and a second transimpedance amplifier (Q2) coupled in a push-pull arrangement. The first transimpedance amplifier further includes a field effect transistor (Q3) as an active load so as to provide feedback and the second transimpedance amplifier further includes a field effect transistor (Q4) as an active load so as to provide feedback.
L'invention concerne un circuit amplificateur d'amplificateur de ligne de câblodiffusion, qui comporte un premier amplificateur en cascade (Q1, Q3) et un second amplificateur en cascade (Q2, Q4) couplé selon une configuration push-pull. Un autre circuit amplificateur comporte un premier amplificateur d'adaptation d'inhérence (Q1) et un second amplificateur d'adaptation d'impédance (Q2) couplés selon une configuration push-pull. Le premier amplificateur d'adaptation d'impédance comporte également un transistor à effet de champ (Q3) faisant office de charge active pour assurer une rétroaction, et le second amplificateur d'adaptation d'impédance comporte un transistor à effet de champ (Q4) faisant office de charge active pour assurer une rétroaction. |
