PROBLEM TO BE SOLVED: To provide an active circuit having improved linearity, utilizing a main circuit unit and an auxiliary circuit unit, in relation to improved linearity of active circuit. SOLUTION: The active circuit includes a main circuit unit, comprising a common gate circuit having a drain terminal through which an output signal is outputted with respect an input signal, an auxiliary circuit unit having a common gate circuit, in order to assist the linearity of the main circuit unit; a biasing unit for biasing the main circuit unit and the auxiliary circuit unit, respectively; and load terminals connected to the output stages of the main circuit unit and the auxiliary circuit unit. The output stages of the main circuit unit and of the auxiliary circuit unit are parallel-coupled. COPYRIGHT: (C)2006,JPO&NCIPI
