摘要：

An up-conversion mixer has been designed for 0.7-2.6GHz multi-mode and multi-standard RF subsystem working under 1.8V voltage based on TSMC 0.18 mu m process in this paper. The circuit is based on the use of pseudo-differential structure of the Gilbert cell, and in order to increase the gain and linearity, is using a complementary trans-conductance current bleeding structure. In addition, a T-type LC networks can reduce the effect of the parasitic capacitance of the LO switching pairs, and make the linearity of the high-frequency greatly improved. Simulation results show that the circuit is working at 0.7-2.6GHz, the gain of the up-conversion is 9.5-9.7dB, the IIP3 of the circuit is 11.4-12.2dBm, and NF is 13.1-13.5dBm.
