【Abstract】 A 2.4 GHz CMOS dual balanced mixer based on the Gilbert cell is designed. The design procedure and simulation results are presented. RF, LO and IF frequencies are 2.4 GHz, 2.41 GHz and 10 MHz, respectively. With 2.5 V supply voltage, the described mixer has achieved a conversion gain of 11.095 dB, a noise figure of 8.836 dB, 1 dB compression point of -13.6 dBm, and IIP3 of -3.72 dBm. Power consumption in the mixer core is 13.5 mW. This mixer was fabricated using a TSMC 0.25 μm CMOS technology with a size of 1 mm×1 mm.更多还原
