In this paper a new high-linear CMOS mixer is proposed. A well-known low voltage CMOS multiplier structure is used for mixer application in this paper and its linearity is provided by adjusting the value of a resistor, sizing the aspect ratio of a PMOS transistor and adding a proper value of inductor at the input stage. In simulation, a supply voltage as low as 1 V is applied to the circuit. Simulation results of improved mixer in a 0.18-μm CMOS technology illustrate 14 dB increases in IIP3 and also an increase around 1.4 dB is obtained in conversion gain. Furthermore, additional components which are used for improving linearity would not increase the power consumption and area significantly.

AbstractThis paper describes a low voltage low power (LV-LP) folded mixer for S-band wireless applications. The proposed mixer could convert a 10 MHz intermediate frequency (IF) signal to a 2.4 GHz RF signal with a local oscillator (LO) power of 0 dBm at 2.39 GHz. The comparison with the previous reported mixers shows that the proposed mixer has the advantages of lower voltage, lower power consumption and higher conversion gain than most of the other works. Simulation results demonstrate that the mixer a remarkable conversion gain of 10.5 dB while consuming only 0.65 mW DC power from a 0.8 V supply voltage. The input-referred third-order intercept point (IIP3) of the mixer is 3.75 dBm, and the chip area is only 0.525 mm
