介绍了一种采用双平衡无源混频器的低功耗、低闪烁噪声直接转换接收机。将深井垂直npn双极结晶体管置于中频放大器的输入级，以降低0.18 um标准CMOS工艺中的闪烁噪声。因此，当本端功率为10 dBm，噪声系数为7 db时，转换增益达到50 db。在1.8 V电压下，总功耗为9.4 mW。
This paper demonstrates a low-power and low-flicker-noise direct-conversion receiver using double-balanced passive mixer. The deep-n-well vertical-NPN bipolar junction transistor is placed as at the input stage of the IF amplifier to reduce the flicker noise in the 0.18 um standard CMOS process. As a result, conversion gain achieves 50-dB gain when the LO power is 10 dBm and the noise figure is 7-dB at 100 kHz. The totally power consumption is 9.4 mW at 1.8 V voltage supply.
