Analysis for Dynamic of Analog Circuits by using HSPN
نویسندگان
چکیده
Since the ability to describe dynamic in high level, Petri Nets has already been used extensively in logic circuits and systems community for state analysis. As others formal methods, extending Petri Nets to analog circuits analysis requires continuous feature enhanced. In this paper, the object of study is dynamic of circuits with random nonlinear feature (such as random noise and random interface) by using a Hybrid Statistical Petri Net (HSPN). A formal definition of hybrid Petri Net is derived from hybrid automata to model the dynamic of nonlinear analog circuits. Furthermore, we improve the hybrid Petri Net to abstract the statistical feature by enhancing the ability of describe random continuous transition. And a formal definition of the novel Hybrid Statistical Petri Net is presented. Within this HSPN, the fundamental method of analyzing the dynamic of random analog circuits is studied. A sample circuit with random noise illustrates this technique. Key–Words: Petri Nets, Random noise, Dynamic, Analog circuits, Hybrid Automata, Formal methods, Model

In this paper, a new circuit scheme is proposed to reduce the power consumption of dynamic circuits. In the proposed circuit, an NMOS keeper transistor is used to maintain the voltage level in the output node against charge sharing, leakage current and noise sources. Using the proposed keeper scheme, the voltage swing on the dynamic node is lowered to reduce the power consumption of wide fan-in...
