Abstract :
This paper presents the design and implementation of a low-voltage down-conversion mixer in 65 nm CMOS technology for UWB applications. The folded circuit topology with AC-coupled inverter based RF transconductance stage operates under low voltage conditions of 1.2 V with a peak gain of 14.5 dB and a 3-dB-bandwidth from 1 GHz to 10.5 GHz with 1 dBm LO power. The input referred compression point is better than -16.5 dBm with an oIP3 of 7 dBm at 2 GHz. The minimum DSB noise figure is 6.5 dB with a flicker-noise corner frequency of 2 MHz. The mixer draws 12 mA from a power supply of 1.2 V leading to a power dissipation of only 14.4 mW.
