## Abstract This article presents a direct down‐conversion mixer for ultra‐wideband systems on 0.18 μm 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. Effe

## Abstract A 1–11 GHz wideband low‐noise amplifier (LNA) with good phase linearity properties (group‐delay variation is only ±35.56 ps across the 3.1–10.6 GHz band of interest) using standard 0.18 μm CMOS technology is reported. To enhance the bandwidth for achieving both high and flat gain and sm
## Abstract In this article, we demonstrate a miniaturized high‐linearity (IIP3 = 8 dBm at 4 GHz) 3–5‐GHz ultrawideband low‐noise amplifier (LNA) implemented in a standard 0.18‐μm CMOS technology. The inductive‐series peaking technique was used to enhance the gain and bandwidth performances of the
