Abstract :
A CMOS down-conversion mixer, using a current mode multiplication technique, is demonstrated in this paper. Apart from low voltage operation, the new mixer has a very good linearity; the measured IIP3 (third-order input intercept point) is equal to 9.5 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 of the mixer is 3 mW.
