A High Linear And Low Noise CMOS RF Front-End For 2.4GHz ZigBee Applications
نویسندگان
چکیده
A 2.4 GHz CMOS RF front-end using for ZigBee application is described. The front-end consists of a low noise amplifier and a down-mixer and uses a 2 MHz IF frequency. A common source with resistive feedback and an inductive degeneration are adopted for a low noise amplifier, and a 20 dB gain control step is digitally controlled. A passive mixer for low current consumption is employed. The RF front-end is implemented in 0.18 μm 1P6M CMOS process. The measured performance is 4.44 dB NF and -6.5 dBm IIP3 while consuming 3.28 mA current from a 1.8 V supply.

Development of Cmos Coplanar Waveguide Matching Circuit for Rf Front-end
For realizing a single chip microwave front-end, we studied the new design theory of impedance matching circuits for a Si-CMOS low noise amplifier (LNA) or power amplifier (PA), which are composed of coplanar waveguide (CPW) meanderline resonators and impedance inverters. We also present the simulated performances of CMOS-LNA or PA connected with input and output matching circuits. Finally, we ...

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 ...
