A 2 GHz Highly Linear Downconversion Mixer in 0.18- m CMOS
نویسندگان
چکیده
This paper describes a 2 GHz CMOS active balanced downconversion I/Q mixer in a TSMC0.18m process for a WCDMA receiver. The mixer achieves a conversion gain of 16 dB and a double side band (DSB) NF of 13.8 dB. The mixer's IIP3 is 12.12 dBm. It consumes approximately 5 mA of current from a 1.8-V power supply. The 12.12 dBm IIP3 fulfils the UMTS requirements for a mixer design.
