In this paper, we propose a method using mean-field neural networks to solve the placement problem for the layout design of analog integrated circuits. By means of the energy function, our method can not only meet the basic requirements of placement, but also handle the symmetry and proximity constraints that are special for analog layouts. Compared with other work, our experimental results show this...
In this paper, broadband frequency doubler employing lead-beam Schottky diodes in a planar balun configuration, consisted of coplanar waveguide, slot-line and micro-strip, is presented. Good performance for output frequency up to K-band (16.5 ~ 25 GHz) are obtained by utilizing some available commercial CAD software. This low-cost multiplier is useful to generate the wide band local oscillator signals...
