Abstract :
This paper proposes the design of a low flicker noise and high input-referred IP2 (IIP2) down-conversion mixer for Zero-IF GSM receiver in 0.18um CMOS process. The current driven passive mixer topology is adopted due to its low flicker noise and high linearity instincts. Simulation results show that this mixer achieves a conversion gain of 23.1dB with 940MHz local oscillator input signal, a flicker noise corner frequency of 2.5KHz and out of band IIP2 above 70dBm at the total current of 17mA.
