Abstract :
This paper presents a 1.2 V 900 MHz CMOS mixer circuit using current mode multiplication. Besides the low voltage operation, the new mixer has a very good linearity, and the measured IIP3 is equal to 10 dBm. The new mixer-circuit is specially designed for low voltage communication circuits using RF CMOS. The operating voltage is 1.2 V and the measured power consumption is 3 mW.
