Analog VLSI Implementations of Continuous - Time
نویسندگان
چکیده
The continuous-time implementation of the popular transversal lter is problematic since it is impossible to implement an ideal time delay in continuous-time hardware. We believe that building an ideal time delay would not be worthwhile anyway since the ideal time delay has shown to be inferior to low-pass (Gamma) and all-pass (Laguerre) stages in discrete-time simulations. We demonstrate feedforward analog VLSI implementations of the Gamma and Laguerre memory structures and show measurements of their performance. We also show through simulation of a system identiication problem that the La-guerre lter is expected to converge faster and be more robust to the noise and oosets that we expect in an analog VLSI implementation.

متن کاملSystem implementations of analog VLSI velocity sensors
We present three di erent architectures that make use of analog VLSI velocity sensors for detecting the focus of expansion, time to contact and motion discontinuities respectively. For each of the architectures proposed we describe the functionality of their component modules and their principles of operation. Data measurements obtained from the VLSI chips developed demonstrate their correct pe...

The long-term goal of our laboratory is the development of analog resistive network-based VLSI implementations of early and intermediate vision algorithms. We demonstrate an experimental circuit for smoothing and segmenting noisy and sparse depth data using the resistive fuse and a 1-D edge-detection circuit for computing zero-crossings using two resistive grids with different spaceconstants.

متن کاملOn Fault Probabilities and Yield Models for Analog VLSI Neural Networks
We investigate the estimation of fault probabilities and yield for analog VLSI implementations of neural computation. Our analysis is limited to structures that can be mapped directly onto silicon as truly distributed parallel processing systems. Our work improves on the framework suggested recently by Feltham and Maly [3] and is also applicable to analog or mixed analog/digital VLSI systems.
