Abstract :
The design of broadband feedback MMIC LNA using a new interactive "visual" technique is presented. The technique allows the fast and convenient design of amplifiers with compensation/feedback two-terminal networks taking into account a simultaneous set of performances, including the gain, gain flatness, noise figure, input and output return losses, and stability. With "visual" CAD tools, AMP-CF and LOCUS, a 2-10 GHz single-stage MMIC LNA has been designed and implemented in 0.2 μm HEMT GaAs technology, providing gain 11.7±1.1 dB, noise figure 2.2 dB, input and output return losses -9.6 dB and -11.7 dB, respectively.
