inductorless high isolation 2.4-ghz cmos mixer with high conversion gain and 2.4-ghz low power

This paper proposes a 2.4 ghz active mixer without passive inductor for the transceiver system. taking into account the design requirements of the mixer, a double-balanced down-conversion structure with active inductor and negative resistance is designed. the proposed mixer with 130 nm cmos technology is designed and simulated using cadence software at 1.5 v supply voltage. although we had to compromise conversion gain with linearity, we were able to achieve very high conversion gain with average linearity. based on the results of post-layout simulations, the conversion gain of 27.57 db, iip3 equal to -7.88 dbm, 1-db compression point equal to -17.34 dbm and iip2 equal to 44.22 dbm with power consumption of 2.5 mw was obtained for the proposed mixer. the chip size without input and output pads is 95.18 µm × 117.68 µm, which leads to a chip area of 0.0112mm2.
