Abstract:	摘要： A 5 GHz double balanced mixer (DBM) is implemented in standard 90 nm CMOS low-power technology. A novel low-voltage self-bias current reuse technique is proposed in the RF transconductance stage to obtain better third-order intermodulation intercept point (IIP 3 ) and conversion gain (CG) when considering the process variations. The DBM achieves a CG of 12 dB, a noise figure (NF) of 10.6 dB and port-to-port isolations of better than 50 dB. The input second-order (IIP 2 ) and IIP 3 are 48 dBm and 4 dBm, respectively. Two I/Q DBMs are then integrated with a differential low-noise amplifier (DLNA) and a poly-phase filter, to from a direct-conversion receiver (DCR). The DCR achieves a CG of 26 dB with an NF of 2.7 dB at 21 mW power consumption from a 1 V supply voltage. The port-to-port isolations are better than 50 dB. The IIP 2 and the IIP 3 of the DCR are 33 dBm and -12 dBm, respectively. 其他題名： TCSI 出版者： New York: IEEE 出版日期： 2012-06-01 出處： IEEE transactions on circuits and systems.
