Abstract :
A novel mixer topology is proposed. The proposed mixer bleeds the driver stage current using a current source, the current source being used as part of the driver stage. A design example is given of a 900 MHz down-conversion mixer using a 0.35 μm CMOS process. Comparison with conventional mixers shows that the topology leads to better performance in terms of conversion gain, linearity, noise figure, and LO isolation
