  ABSTRACT: A double balanced Gilbert-cell class-A amplifier bleeding mixer (DBGC CAAB mixer) is proposed and implemented. The injection current is utilized to amplify the local oscillator (LO) signal to improve the performance of the transconductor stage. The DBGC CAAB mixer achieves a conversion gain of 17.5 dB at -14 dBm LO power, and the noise figure is suppressed from 45 dB to 10.7 dB. It is important to stress that the new configuration will not drain additional power in contrast to the former current bleeding mixers. This topology dramatically relieves the requirement of the LO power. The DBGC CAAB mixer is implemented by using 0.18-μm RFCMOS technology and operates at the 2.4 GHz ISM application with 10 MHz intermediate frequency. The power consumption is 12 mA at 1.5 V supply voltage. The DBGC CAAB mixer features the highest FOM figure within a wide range of LO power.
