Abstract: PURPOSE: A wideband active circuit with a feedback structure is provided to remarkably improve the bandwidth by forming a feedback structure which feeds back a signal of an output terminal to an active load. CONSTITUTION: An active load unit(100) provides load varying according to control voltage, and an active circuit unit(200) is connected between the active load unit and the ground. The active circuit unit outputs a signal corresponding to a preset bandwidth among the input signals. A feedback circuit unit(300) is formed between an output terminal of the active circuit unit and the active load unit, and supplies the signal of the output terminal of the active circuit unit to the active load unit. The active load unit is formed between the power voltage terminal and an output terminal in cascode structure.
