This paper presents an ultra-wideband (UWB) low noise amplifier (LNA) consuming 2.2-mW core dc power for 6-8.5GHz wireless applications. A common-gate input stage is cascaded with a common-source second stage to perform input impedance matching and wideband stagger-tuning amplification, while the current-reuse topology minimizes the dc power dissipation. The design method used to achieve flat-g...

In this paper, a CMOS low-noise amplifier (LNA) with a new input matching topology has been proposed, analyzed and measured. The input matching network is designed through the technique of capacitive feedback matching network. The proposed LNA which is implemented in a 0:18-mm1P6M CMOS technology is operated at the frequency of 12.8GHz. It has a gain S21 of 13.2 dB, a noise figure (NF) of 4.57 ...

The main focus of this paper is to design a “Low noise amplifier” for radio frequency applications using MOS 180nm technology. In modern RF electronics, we rarely design an LNA in isolation. Rather, we view and design the RF chain as one entity, performing many iterations among the stages. A low power MOS low noise amplifier (LNA) working at 2.4GHz for ZigBee communication is presented in this ...

Implemented in a ...

Abstract: The effect of using a tuning inductance on the performance of a Gilbert cell-based two level transistor CMOS sub-harmonic mixer is investigated. The tuning inductor used between the RF and LO switching stages causes conversion gain enhancement and noise figure improvement. Additionally, it compensates LO distortion due to the phase mismatch of LO signals in the sub-harmonic mixer. The...
