An ultrawideband CMOS distributed receiver front-end utilizing cascade gain cell structure is designed in Jazz 0.18-mu m 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 x 1.0 mm(2) including on-wafer pads and consumes 170 mA from 1.8-V voltage supply.
