Artykuł prezentuje metodę projektowania przetwornika cyfrowo-analogowego małej mocy w technice przełączanych prądów. W pracy zaproponowana została architektura układu bazująca na wykorzystaniu wielowyjściowego zwierciadła prądowego, którego parametry obliczane są za pomocą metody Hooke’a-Jeevesa. Przeanalizowany został przykład realizacji układu w technologii TSMC 90nm. Autorzy zamieścili rozwiązanie...
The paper deals with circuit parameter fitting in gyrator- capacitor prototypes of analogue filters. The genetic solver available in Matlab environment altogether with dedicated software was used for this task. There is the general idea presented as well as some experimental results that prove the feasibility of this approach. The investigations were made over classical single input, single output...
The paper presents a low sensitive design strategy of analog filter pairs based on a gyrator-capacitor prototype circuit. The prototype circuit is synthesized with the use of topological analysis described in detail in the paper. A set of nonlinear algebraic equations is formulated by matching of coefficients obtained from the symbolic analysis with coefficients from the given transfer functions....
