Abstract
A high performance CMOS mixer based on current bleeding topology is implemented. The mixer has high gain and low noise that is attributed to the effect of current injection and local oscillator (LO) amplification. The conversion gain of the mixer is 17.5 dB at-14 dBm LO power and the noise figure is 10.5 dB. The mixer is implemented by a 0.18-μm CMOS process. The operating frequency is 2.4 GHz with 10 MHz intermediate frequency. The circuit drains 12 mA current from a 1.5 V supply voltage. The implemented mixer can be used in many 2.4GHz applications including ZigBee and Z Wave.
