An ultra low power and low voltage down conversion mixer is presented in this paper for the frequency band of 1.8-2.4 GHz. Designed in 0.18 mu m CMOS technology, the double balanced proposed mixer is composed by two cascaded stages. The first one is based on cross coupled capacitors technique in current reused topology providing a high voltage gain, while the second one employs a current reused transducer coupled to LO driven inverters to perform the down conversion. All the devices operate on moderate inversion for better trade-off between gain, linearity, and low power consumption. The post layout simulation shows a 23 dB of voltage gain conversion, an IIP3 of -2 dBm, with 300 mu W of power consumption under 0.9 V voltage supply.
