A low-power adaptive integrate-and-fire neuron circuit
We present a low-power analog circuit for implementing a model of a leaky integrate and fire neuron. Next to being optimized for low-power consumption, the proposed circuit inclu...

Optimization of shield structures in analog integrated circuits
The effect of shield structures for local wirings of analog integrated circuits on crosstalk is determined by electromagnetic simulation. The crosstalk of parallel wirings is redu...

A 5th order Volterra study of a 30W LDMOS power amplifier
A 30 W LDMOS is modeled using a 5th order polynomial model. The polynomial model is compared to the largesignal MET model using harmonic balance, and as the results agreed very we...

Applications of nonlinear dynamics to the turbo decoding algorithm
In this paper, we treat the turbo decoding algorithm as a dynamical system parameterized by the SNR (signal-to-noise ratio). A whole range of nonlinear phenomena, including chaos ...
