Abstract
A two-stage down-conversion architecture for 3.1-8 GHz ultra-wideband receiver front-end is designed which uses a local oscillator frequency equal to half the input frequency. The down-conversion technique is performed in two steps based on half-RF architecture to produce baseband signal. The proposed technique is implemented in 0.18 μm CMOS technology which achieves a conversion gain ranges from 36.1-32.4 dB and noise figure of 5.4-8.3 dB across the bandwidth.
