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