An ultrawideband CMOS distributed receiver front‐end utilizing cascade gain cell structure is designed in Jazz 0.18‐μm CMOS process.The proposed distributed front‐end, fully integrating a low‐noise amplifier (LNA) and mixer together, demonstrates 11.5–14 dB gain, 5–6.5 dB noise figure and more than 9‐dB RF/LO return loss over 2–17 GHz with a fixed IF frequency of 500 MHz and LO power of 5 dBm. The entire circuit occupies 1.7 × 1.0 mm 2 including on‐wafer pads and consumes 170 mA from 1.8‐V voltage supply. © 2010 Wiley Periodicals, Inc.
