A High-linearity Low-noise Figure Active Mixer in 018um CMOs

摘要

This article presents a CMOS active down-conversion mixer with high linearity and low noise figure for 2.4GHz Bluetooth receiver systems. This mixer's design methodology is aimed to achieve high linearity and low noise figure. The designed toplogy of down-converter mixer realizes conversion gain of 8dB, input third-order intercept point (IIP3) of 17.39dB, and single side-band noise figure (NF) of 5.61dB respectively. It is show that the designed mixer achieves high quality. The mixer is implemented by TSMC 0.18um CMOS process using a 3V power supply.
