A third-order transconductance (gm3) cancellation is utilized to obtain a highly linear mixer. Transistors obtain good linearity with complementary gm3 values. The transistor thus obtained can be operated in a wide bandwidth and is applicable to various frequency specifications of systems, like Bluetooth, wireless LAN, Ultra-Wide Band (UWB), etc. Then the transistors are applied to design a transconductance-stage input of the mixer. Hence, the present invention can be widely applied to receiver modules and be realized with a low-cost CMOS transistor.
