Abstract :
This paper presents a 2 GHz image rejection (IR) downconverter implemented in a 0.65 /spl mu/m CMOS technology. It maintains high IR ratio against the process and temperature variations if the on-chip passive RC components are relatively matched. The experimental circuit provides an IR ratio of 40.8 dB without any off-chip filtering or tuning, and dissipates 91 mW at 3.3 V.
