- Abstract
- This article presents a direct down-conversion mixer for ultra-wideband systems on 0.18 mu m RF CMOS process. The proposed mixer uses a current bleeding technique and an internal resonant inductor to improve the conversion gain and noise figure of the conventional Gilbert-cell mixer. Effects of each technique are compared on mixer's noise performance. Measured results show the conversion gain of 7.510. 1 dB and the double side-band noise figure of 8.8-12.5 dB at Band 1 (3.168-3.696 GHz) and the gain of - 1.4 to 1.6 dB and the double side-band noise figure of 12.2-17.6 dB at Band 13 (9.76810.296 GHz). The circuit operates at the supply voltage of 1.8 V and dissipates 13.24 mW.
