• This paper presents a high performance wideband CMOS direct down-conversion mixer for UWB based on 0.18μm CMOS technology. The proposed mixer uses the current bleeding technique and an extra resonant inductor to improve the conversion gain, noise figure (NF) and linearity. Also, with an extra inductor and the careful choosing of transistor sizes, the mixer has a very low flicker noise. The shunt resistor matching is applied to have a 528MHz bandwidth matching at 50Ohm. The simulation results show the voltage conversion gain of 20.5dB, the double-side band NF of 5.6dB. Two-tone test result indicates 11.25dBm of IIP3 and higher than 70dBm of IIP2. The circuit operates at the supply voltage of 1.8V, and dissipates 11.5mW.
