A 2.4 GHz double balanced differential input single output low power transmitting mixer In TSMC 180nm CMOS RF process

Abstract

In this paper, a high gain low-power upconversion Gilbert cell mixer, designed in 180nm RF CMOS process, is proposed to realize the transmitter front-end working at 2.4 GHz frequency. The proposed mixer can convert a 100 MHz intermediate frequency (IF) signal into a 2.4 GHz RF signal, with a local oscillator power of 5 dBm at 2.3 GHz. A comparison with conventional other up-conversion mixers shows high performance. Simulation results demonstrate that at 2.4 GHz, the circuit provides 28.40 dB of conversion gain and the input-referred third-order intercept point (IIP3) of -17.78 dBm. The circuit consumed 8.660mW power and it is laid out using Cadence Virtuoso layout editor of size 0.229mmx0.205mm.
