Abstract
In this paper, a 2.4 GHz low-voltage CMOS double-balanced down-conversion mixer using neutralization technique has been proposed and verified by circuit simulations and measurements. The grounded source structure was used for low-voltage operation. The neutralization technique was used to improve a conversion gain. The proposed mixer is fabricated in $0.25{\mu}m$ CMOS process for a 2.4 GHz wireless receiver. The mixer consumes 1.94 mW and gives conversion gain of 5.66 dB, input IP3 of 0.7 dBm and P1dB of -11.2 dBm at 1.5 V power supply. Measured results for the designed mixer show improved conversion gain of 2.86 dB over conventional mixer of grounded source structure.
