摘 要: | This paper presents a reconfigurable quadrature passive mixer for multimode multistandard receivers. By using controllable transconductor and transimpedance-amplifier stages, the voltage conversion gain of the mixer is reconfigured according to the requirement of the selected communication standard Other characteristics such as noises figure, linearity and power consumption are also reconfigured consequently. The design concept is verified by implementing a quadrature passive mixer in 0.18 μm CMOS technology. On wafer measurement results show that, with the input radio frequency ranges from 700 MHz to 2.3 GHz, the mixer achieves a controllable voltage conversion gain from 4 to 22 dB with a step size of 6 dB. The measured maximum ⅡP3 is 8.5 dBm and the minimum noise figure is 8.0 dB. The consumed current for a single branch (I or Q) ranges from 3.1 to 5.6 mA from a 1.8 V supply voltage. The chip occupies an area of 0.71 mm2 including pads.
