| Abstract: | A new simple wide-band mixer exploiting MOSFETs working in the linearity region was presented.The mixer meets the high-linearity,low-voltage and low power consumption requirements of wireless systems and has a wide operating frequency range with standard CMOS technology.Besides,only one single LO input is needed,which solves the problem of single-end to differential transformation.Simulation results show that the circuit has 3.8 mW power consumption,13.8 dB conversion gain,-4 dBm P-1dB point and 12 dB noise figure(NF) under 1.2V voltage supply. |
