Abstract: PURPOSE: A complementary circuit is provided to improve the linearity of a single end type broadband reception circuit and a noise property by applying a current amplification concept to a noise canceling structure. CONSTITUTION: A mixer circuit(600) is composed of a current mirror transconductacne stage(610) and a N channel type differential device switching stage(620). The current mirror transconductacne stage comprises a fifth NMOS transistor and a fifth PMOS transistor. The N channel type differential device switching stage is formed into the differential structure of a 6 NMOS transistor and a 7 NMOS transistor. By mixing a variable gain low noise amplifier with the mixer circuit, a reception circuit or a transmission circuit is formed.
