Generator of current pulses having stable parameters, based on a nonlinear inductor obtained using switched linear capacitors and a gyrator

Emanuel Gluskin

A current-controllable nonlinear inductor with a simple-form but a strongly nonlinear (singular) flux-current characteristic, obtained by means of a switched capacitor unit and a gyrator, is proposed. The unit includes linear capacitors that are switched at some given voltage level(s). It is important for the point of nonlinearity that the moments of switchings are not given a priori, but are defined by the voltage on the switched unit, which is one of the state variables of the circuit. The use of linear elements, and the fact that the circuit does not include physical (magnetic) inductors, makes the circuit reliable and suitable for integrated implementation, which is relevant, in particular, for the realization of multi-element nonlinear circuits. An application of an oscillatory circuit, including such a nonlinear inductor, might also be the generation of current pulses having a stable amplitude. This might be important, e.g., for the operation of solid-state lasers. Numerical simulations of the inductor circuit are in agreement with theoretical propositions.
