Abstract :
This paper deals with the symbolic solution of the switched current circuits. As described, the full graph method of the solution can be used for finding relationships expressing current transfer, too. The summa MC-graph is constructed using two-graphs method in two-phase switching. By comparing the matrix form with results of the Mason´s formula relations for current transfers in all phases are derived. There are discussed various options described transistor memory cells - with loss and lossless transistors and normal transistor current mirror. Evaluation of the graph is simplified if we consider the lossless transistors or if the y21-parameter of one transistor is alpha multiple of second ones.
