Low‐noise, ultra‐wideband (UWB) wireless receiver front‐end circuits were presented in this study. A two‐stage common‐source low‐noise amplifier with wideband input impedance matching network, an active‐balun and a double‐balanced down‐conversion mixer were adopted in the UWB wireless receiver front‐end. The proposed wireless receiver front‐end circuits were implemented in 0.18 μm radio‐frequency‐CMOS process. The maximum down‐conversion power gain of the front‐end is 25.8 dB; minimum single‐sideband noise figure of the front‐end is 4.9 dB over complete UWB band ranging from 3.1 to 10.6 GHz. Power consumption including buffers is 39.2 mW.
