Abstract
Abstract 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.
