摘要:
The present invention relates to improved linearity of an active circuit, and more particularly, to an active circuit having improved linearity using a main circuit unit and an assistant circuit unit. According to the present invention, the common gate circuit includes a main circuit unit consisting of a common gate circuit having a drain terminal through which an input signal is output as an output signal, an assistant 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 assistant circuit unit, respectively, and load stages connected to output stages of the main circuit unit and the assistant circuit unit, wherein the output stages of the main circuit unit and the assistant circuit unit are coupled to each other.
