A high gain and low noise mixer based on current bleeding topology is implemented. The high performance 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 proposed topology dramatically relieves the typically high power requirement of LO. 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.
