176 Myers, Chris J.Direct synthesis of timed asynchronous circuitsThis paper presents a new method to synthesize timed asynchronous circuits directly from the specification without generating a state graph. The synthesis procedure begins with a deterministic graph specification with timing constraints. A timing analysis extracts the timed concurrency and timed cau...1999
177 Myers, Chris J.Architectural synthesis of timed asynchronous systemsThis paper describes a new method for architectural synthesis of timed asynchronous systems. Due to the variable delays associated with asynchronous resources, implicit schedules are created by the addition of supplementary constraints between resources. Since the number of schedules grows exponenti...1999
178 Myers, Chris J.Direct synthesis of timed asynchronous circuitsThis paper presents a new method to synthesize timed asynchronous circuits directly from the specification without generating a state graph.

179 Mathews, V. JohnEqualization of recursive polynomial systemsAbstract-This letter presents some theorems for the exact and pth-order equalization of nonlinear systems described by recursive polynomial input-output relationships.

185 Stevens, KennethRelative timingRelative Timing is introduced as an informal method for aggressive asynchronous design. It is demonstrated on three example circuits (C-Element, FIFO, and RAPPID Tag Unit), facilitating transformations from speed-independent circuits to burst-mode, relative timed, and pulse-mode circuits. Relative ...1999

187 Harrison, Reid R.Floating gate current mirror for gain correction in CMOS translinear circuitsThe exponential behavior of MOSFETs in subthreshold operation has recently been exploited to build CMOS translinear circuits such as multipliers and log-domain filters. A major obstacle in developing a practical CMOS implementation is the variation in threshold voltage between devices. In transline...1999-01-01
188 Harrison, Reid R.Analog VLSI implementation of a visual interneuron: enhanced sensory processing through biophysical modelingFlies are capable of rapid, coordinated flight through unstructured environments. This flight is guided by visual motion information that is extracted from photoreceptors in a robust manner. One feature of the fly's visual processing that adds to this robustness is the saturation of wide-fi_x000...1999-01-01
