Low Voltage Low Power Folded Mixer for S-Band Wireless Applications

Abstract

This 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 2 .
