A new low complexity ultra-wideband 3.1–10.6GHz low noise amplifier (LNA), designed in a chartered 0.18μm RFCMOS technology, is presented in this paper. The ultra-wideband LNA only consists of two simple amplifiers with an inter-stage inductor connected. The first stage utilizing a resistive current reuse and dual inductive degeneration techniques is used to attain a wideband input matching and low...
In this paper, a novel current-mode differential transconductance wide band low noise amplifier (LNA) designed in the chartered 0.18μm CMOS technology is proposed to realize the receiver front-end. The proposed LNA frequency ranges from 4GHz to 6GHz. It utilizes two stage structure, with a current-mirror using inductive series peaking technique to achieve optimized current output. The noise performance...
This paper presents a technique using current-mode approach for a CMOS differential low noise amplifier design, simulated with a TSMC 0.18 ??m RF CMOS process, working at 1.2 V supply. A comparison with conventional voltage-mode LNA shows that this LNA has advantages of low voltage, low power consumption and simple structure. Simulation results demonstrate that at 2.4 GHz, the noise figure is only...
