Abstract :
This paper presents a way of implementing the MOST channels´ Noise Current Cancellation Technique (NCCT) on a mixer for reducing its noise figure, generating a new mixer architecture designed in a 0.18μm RF CMOS UMC technology. The MOST Channel´s Noise Current Cancellation Technique was first time presented. The noise figure performance of the new mixer architecture can be as low as 4.4dB@80MHz or if coils are used 1dB@80MHz noise figure can be reached. The conversion gain of such a mixer is higher than 20dB, the IP3 is -5dBm and the power consumption are smaller than 18mW at 1.8V power supply. All simulations for the new mixer architecture were made with SpectreRF.
