H. Ezzedine et al., NOISE WAVE TECHNIQUES ANALYSIS APPLIED TO VARIOUS PLANAR MICROWAVE ACTIVE-FILTER TOPOLOGIES, INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING, 8(2), 1998, pp. 116-130
This article deals with the improvement of noise figure for various to
pologies of microwave active filters. We show how, using a noise wave
formalism, the noise factor of different filters can be analytically d
erived and effectively minimized. We validate our approach with simula
ted examples for each topology. (C) 1998 John Wiley & Sons, Inc.
