This paper presents noise analysis of a lateral tunneling accelerometer, considering Brownian motion, Nyquist-Johnson and shot noise. The tunneling accelerometer has been fabricated; a low noise differential transresistance amplifier and a digital integral controller have been designed and implemented. Noise analysis has been made based on state space… (More)
High speed synchronous digital systems require large switching currents to facilitate rapid signal transitions. These large currents create voltage drops on the power distribution network and necessitate expensive chip packaging with a large number of supply pins. In this paper we propose a novel technique to reduce the dynamic transient current drawn from… (More)
Variation of power and ground levels affect VLSI circuit performance. Trends in device technology and in packaging have necessitated a revision in conventional delay models. In particular, simple scalable models are needed to predict delays in the presence of uncorrelated power and ground noise. In this paper, we analyze the effect of such noise on signal… (More)
extract parallelism implicit in the input specification Boolean 'guard' functions are used to identify paths where operations have to be scheduled and the execution order of the conditionals is dynamically resolved. An efficient and systematic iterative construction method is presented along with benchmark results.
This paper applies a form of instruction stream interleaving to the problem of high performance real-time systems. Such systems are characterized by high bandwidth, stochastically occurring interrupts as well as high throughput requirements, The DISC computer is based on dynamic interleaving where the next instruction to be executed is dynamically selected… (More)
This paper describes an exact symbolic formulation of control-dependent, resource-constrained scheduling. The technique provides a closed-form solution set in which all satisfying schedules are encapsulated in a compressed OBDD-based representation. This solution format greatly increases the flexibility of the synthesis task by enabling incremental… (More)
This paper describes a new high-level synthesis system based on the hierarchical Production-Based Specification (PBS). Advantages of this form of specification are that the designer does not describe the control flow in terms of explicit states or control variables and that the designer does not describe a particular form of implementation. The… (More)
