Abstract :
Mixer is one of the main modules of a transmitter system, and its performance will heavily impact the functionality of the entire transmitter. Gilbert cell structure can achieve high degree of RF (Radio Frequency) and LO (Local Oscillator) isolation, thus loosening filtering output requirements. This paper presents a up-conversion mixer, designed in a standard TSMC0.13 μm CMOS technology, for 1.8-2.6GHz wideband applications. The up-conversion mixer is configured with the structure of Gilbert Cell and takes advantage of current bleeding. The post simulation results indicated that under 1.2V power supply the conversion gain was more than 1.1dB and the input IP3 was more than 6.45dBm, the total area of the layout is 0.82×0.7 mm2.
