Abstract

A novel 0.13 mum CMOS low-voltage high-linearity mixer for direct-conversion UWB receiver is presented. The topology of the wideband mixer employing a shunt resistor in input-matching network is analyzed in details. A CMOS inverter with current-reuse technology is used in the transconductance stage. The transconductance stage and the switching stage are ac-coupled with capacitors. LC resonators were adapted in design to replace commonly used current sources. The methods of improvement on linearity, gain and noise are analyzed. The ICs were fabricated with SMIC 0.13 mum RFCMOS technology. The measured IIP3 of 10.2 dBm, with a power gain of -4.2 dB, and SSB noise figure of 12 dB were obtained. A low dissipating power of 5.1 mW at 1 V supply voltage was also achieved.
