NONLINEAR SC NETWORK WITH A VOLTAGE COMPARATOR S u ib m a r y

The baalc SC network wlth a comparator controlling aome of ita switches has been ahown. The lnput aignal of the comparator la taken fron lnalde of tha network ao it la poaalble to obtaln nonllnear characteria-tlca without ualng real nonllnear elementa, (for exaeple aemiconductor Junctiona). The models of SC systema realizlng rectifier fuli- end half-ware characterlstlcs and the network restorlng the slgn of the lnput aignal have been ahown. It ls poaalble to obtaln aymmetric and aaymmetrlc blquadrant nonllnear characterlatlca by meana of auch natworka. Reallzation of the atep nonllnearlty wlth aaalgned alopes of partlcular aectors of a stralght lina has been ahown.

The expreaslons allowlng calculatlon of the netwark elementa (capacitiea and swltchlng voltagea of comparatora) have been lntroduced ao lt la poaalble to design the network wlth the nonllnear convex or concave characteriatic. The networka modelllng the functlons square and square root for atep nonllnearlty wlth adequetely aelected slope of partlcular aectora of the linę have been ahown aa an example.
