Abstract

A new fully differential ultra low-voltage, ultra low-power down-converter mixer for ultra wideband application is presented in this paper. This mixer is designed using four-terminal MOS transistors. The radio frequency is applied to source and local-oscillator signal is applied to the gate with body of devices simultaneously. A DTMOS common source amplifier is employed increasing conversion gain. The proposed circuit is designed and simulated in the TSMC 0.18μm CMOS process. The simulation results show that the proposed mixer has a peak conversion gain of 12.3dB with 3dB RF frequency bandwidth from 2GHz to 10.5GHz with a fixed IF frequency of 100MHz. The third-order intermodulation-intercept point (IIP3) varies from -5.2dBm to -7.3dBm between 2-10.5GHz. The proposed mixer consumes only 1.28mW power with 0.5V supply voltage.
