The most general parameter of the electronic circuit is its sensitivity. Sensitivity analysis helps circuit designers to determine boundaries to predict the variations that a particular design variable will generate in a target specifications, if it differs from what is previously assumed. There are two basic methods for calculating the sensitivity: matrix methods and graph methods. The method described in this article is based on a graph, that contains separate input ad output nodes for each phase. This makes it possible to determine the transmission sensitivity even between partial switching phases. The described fully-graph method is suitable for switched current circuits and switched capacitors circuits, too.

“…One way of this solution is the signal flow graphs [11], [12], [13]. Signal-flow graphs technique is very useful tool for the analysis and/or synthesis networks [14], [15] [16], many types of SFG´s and different methods of their derivation have been already proposed [17], [18], [19]. Another possibility of derivation is fully graph method which is described bellow.…”

The second order Sallen-Key low-pass filter structures (so called biquads) in the voltage and the current mode have one common disadvantage. This is a decreasing of the attenuation at high frequencies, because active elements exhibit losses of the amplification. While some solutions for the voltage mode circuits have been already published, but this problem was not satisfactorily solved for circuits working in the current mode. Therefore, this article presents one of the possible solutions of this problem for circuits working in the current mode derived by graph method.
