A layer-encoded interactive evolutionary algorithm (IEA) for optimization of design parameters of a monolithic microwave integrated circuit (MMIC) low noise amplifier is presented. The IEA comprises a combination of the genetic algorithm (GA) and the particle swarm optimization (PSO) technique. The ...
Each band, extending over one octave only, is then accommodated by a low-noise amplifier, to maximize the sensitivity of the system, and after amplification each band is further processed separately. In one realization of an ESM system, banks of contiguous filters are used to examine the ...
The system design along with detailed design of analog signal processing part, containing two cascaded low noise amplifier and a voltage stabilizing circuit, and digital signal processing part, constituted by some low cost basic digital circuit elements, are described. Extensive experiments are conducted...
[36]. The proposed antenna, which enables dual-band operation in GPS and Iridium bands, is additionally equipped with an active circuit, containing a low noise amplifier (LNA) chip, conveniently integrated on the feed plane on the back side of the structure, enhancing the overall performance. ...
Keywords: LNA; current reuse; gain adjustable; noise 1. Introduction The low noise amplifier (LNA) is one of the important components in the front end of the radar receiver, and its noise figure directly affects the sensitivity of the receiver. At the same time, it is hoped that it has ...
Both branches are then fed to the mixer, followed by a low-pass filter (LPF), a low-noise amplifier (LNA), and a beat frequency (audio) FFT spectrum analyzer. The signals at the input ports of the mixer can be written as follows: 𝑣1(𝑡)=𝐴1sin[𝜔(𝑡−𝜏)+𝜙(...
