This paper presents a low voltage low power high linearity quadrature mixer for software defined radio applications in a 90nm CMOS technology. A 7-dB improvement of input-referred 3rd-order intermodulation point (IIP3) is achieved by using a differential gm″ (the second derivation of transconductanc...
