A 3.3V 30mW 200MHz CMOS Upconversion Mixer using Replica Transconductor

The lower transconductance of CMOS devices limits the implementation of upconversion mixer especially for lower loads. In this paper, a power efficient linear upconverter is presented. Using replica transconductor, the linear range is extended up to the limit. The circuit was implemented using 0.8 μ...

Summary:The lower transconductance of CMOS devices limits the implementation of upconversion mixer especially for lower loads. In this paper, a power efficient linear upconverter is presented. Using replica transconductor, the linear range is extended up to the limit. The circuit was implemented using 0.8 μm CMOS technology. The power consumption is 30 mW with 3.3 V supply. The mixer operates properly above 200 MHz.
