A 2-6 GHz WiMAX low noise amplifier (LNA) is designed and implemented in 0.18-??m CMOS process. This low noise amplifier utilizes a current-reused technique, and a high-pass input matching network. The LNA presents a maximum power gain of 18.4 dB at 2 GHz. The minimum noise figure (NF) is 2.1dB. S11 is less than -16 dB. The total power consumption is 17.4 mW under a 1.8 V power supply. The chip size...
A 1-5 GHz ultra-wideband CMOS low-noise amplifier (LNA) is presented. A common-gate topology is adopted for the input stage to achieve wideband input matching, while a cascode stage is used as the second stage to provide power gain at high frequencies. By using two inductors in the LNA, a small chip area is obtained. The LNA has been fabricated in a standard 0.18 μm CMOS technology. The measured maximum...
In this paper, we present a new wideband low noise amplifier which operate in UHF band for spectral sensing in the receiver of cognitive radios. The circuit employs the noise-canceling technique, and can achieve the higher gain and lower power dissipation. The method of shunt-resistive feedback is adopted for achieving a broad bandwidth. The LNA is designed by the CMOS 0.18 um RF technology. Simulated...
Presented is a novel active-balun low noise amplifier (LNA) with forestage-poststage gain controls for VHF/UHF mobile-TV tuners. It consists of two passive attenuators inter-operating with an active core to optimize the RF performances under different reception scenarios. The forestage is a MOS-based attenuator configured in a way that, at all attenuation levels, a broadband input impedance match...
A low power inductorless variable gain amplifier (VGA) for wideband communication systems is presented in this paper. It is a resistor feedback close-loop amplifier based on a proposed wideband operational amplifier. The operational amplifier is constructed by an artificially differential N/P complementary cascode amplifying stage for high gain, and a self-biased N/P complementary source follower...
