Self-powered sensing refers to an energy scavenging approach where the power for sensing, computation and storage is harvested directly from the signal being sensed. Presented is a 16-transistor CMOS circuit that can be used for the self-powered sensing of strain-rates using signals produced by piezoelectric energy scavengers. By exploiting operational primitives inherent in impact-ionised hot-...

0a thin film of cobalt hexacyanoferrate (cohcf), an analogue of mixed-valence prussian blue, was deposited electrochemically on the glassy carbon, platinum and gold electrode surfaces in 0.5m kc1 solution. the electrochemical behavior of these modified electrodes show three couples of redox peaks by cv in a supporting electrolyte solution of 0.5m nacl, whereas for au modified electrode only one...

Transient Response Testing has been shown to be a very powerful and economical functional test technique for linear analogue cells in mixed-signal systems. Recently this work has been extended to non-linear analogue circuits by treating Transient Response Testing as a structural test technique and employing optimised and reduced fault sets that are derived from Inductive Fault Analysis and circ...

Ohletz [1] described a mixed signal circuit architecture which can be reconfigured to allow built-inself-test of both analogue and digital parts. In testing the analogue section an on board test signal can be generated from digital components, the analogue test output fed through an A-D converter and the resulting digital bit stream used as the input to a digital signature analyser. Clearly suc...

Consider a variant of the graph diameter of a polyhedron where each step in a walk between two vertices travels maximally in a circuit direction instead of along incident edges. Here circuit directions are non-trivial solutions to minimally-dependent subsystems of the presentation of the polyhedron. These can be understood as the set of all possible edge directions, including edges that may ari...

SystemC is Hardware Description Language HDL for digital systems. An extension is proposed in this paper to extended the capabilities of SystemC to allow modelling of analogue and mixed-signal systems. The proposed extension provides a variety of abstraction levels, from system level to circuit level. In order to comply with the SystemC simulation cycle semantics, the analogue kernel is linked ...

Circuit algebras, introduced by Bar-Natan and the first author, are a generalization of Jones's planar in which one drops planarity condition on “connection diagrams”. They provide useful language for study virtual welded tangles low-dimensional topology. In this note, we present circuit algebra analogue well-known classification algebras as pivotal categories with self-dual generator. Our main...
