NARROW PULSE FORMATION USING NONLINEAR LC LADDER NETWORKS

Soliton propagation in a nonlinear lossy LC ladder network has been st udied We propose a quadratic polynomial expression to model the C-V ch aracteristic of the nonlinear capacitor of the LC ladder network. This fits the experimental C-V data better over a wider range of the appli ed voltage, compared with the conventionally used formulae. Using this C-V expression, the Korteweg-de Vries (KdV) equation with a loss term has been obtained. This nonlinear equation has been solved by employi ng a novel technique that is based on Fourier series analysis. We have investigated the effects of bias voltage on the soliton pulse width a nd peak voltage and found a good agreement between the theoretical and experimental results.
