In this paper, low voltage high gain up-conversion mixer, designed in 90nm CMOS technology, is proposed to work in the frequency band of 2.4 GHz. Current bleeding technique and current mirror topology are used in the upconversion mixer. Conversion Of an input of 100 MHz Given as intermediate frequency signal to an output of 2.4 GHz radio frequency signal is done by the proposed mixer with a local oscillator frequency signal of 2.3 GHz. Advantages of the proposed mixer are low voltage and high
