Stevens, Kenneth | Relative timing | Abstract-Relative timing (RT) is introduced as a method for asynchronous design. Timing requirements of a circuit are made explicit using relative timing. Timing can be directly added, removed, and optimized using this style. RT synthesis and verification are demonstrated on three example circuits,... | | 2003 |

Sanchez, Thomas W. | Walling in or walling out: gated communities | It has been four decades since the United States legally outlawed all forms of public discrimination - in housing, education, transportation, and accommodations. Yet today, we are seeing a new form of discrimination -- the gated, walled, private community. Americans are electing to live behind wall... | | 2007 |

Khan, Faisal Habib | Quantifying device degradation in live power converters using SSTDR assisted impedance Matrix | A noninterfering measurement technique designed around spread spectrum time domain reflectometry (SSTDR) has been proposed in this paper to identify the level of aging associated with power semiconductor switches inside a live converter circuit. Power MOSFETs are one of the most age-sensitive compon... | | 2014-01-01 |

Davis, Al | An introduction to asynchronous circuit design | The purpose of this monograph is to provide both an introduction to field of asynchronous digital circuit design and an overview of the practical state of the art in 1997. In the early days of digital circuit design, little distinction was made between synchronous and asynchronous circuits. However,... | Asynchronous circuit design | 1997 |

Brunvand, Erik L. | Peephole optimization of asynchronous macromodule networks | Most high level synthesis tools for asynchronous circuits take descriptions in concurrent hardware description languages and generate networks of macromodules or handshake components. In this paper we describe a peephole optimizer for such macromodule networks that often effects area and/or time im... | | 1994 |

Lupton, John Mark | Time-gated electroluminescence spectroscopy of polymer light-emitting diodes as a probe of carrier dynamics and trapping | We present time-gated electroluminescence (EL) spectroscopy of a polyfluorene-based conjugated polymer. The technique is shown to be sensitive enough to pick out impurity emission orders of magnitude weaker than the cw emission. By considering the temperature dependence of the delayed emission spect... | Time-gated electroluminescence spectroscopy; Carrier dynamics; Trapping; Delayed emission | 2002-04 |

Furse, Cynthia M. | Capacitance and inductance sensor circuits for detecting the lengths of open- and short-circuited wires | The length of an open- or short-circuited wire is linearly proportional to the capacitance or inductance of the wire, respectively. Several types of simple and inexpensive circuits are introduced to measure these values. Open-circuited (capacitance) measurements are very effective.

Stevens, Kenneth | Characterization of asynchronous templates for integration into clocked CAD flows | Asynchronous circuit design can result in substantial benefits of reduced power, improved performance, and high modularity. However, asynchronous design styles are largely incompatible with clocked CAD, which has prevented wide-scale adoption. The key incompatibility is timing. Thus most commercial... | | 2009 |
