An analog integrated circuit for motion detection

1998 Second International Conference. Knowledge-Based Intelligent Electronic Systems. Proceedings KES'98 (Cat. No.98EX111), 2002
It was clarified in motion detection that the analog network based on a biological system works in a similar manner to a simplified algorithm of the optical flow. The proposed network is constructed by combining simple fundamental circuits called VSC. The direction and speed of motion can be detected with the network.

Techniques for synthesis of analog integrated circuits

IEEE Design & Test of Computers, 1992
The CAD tools that have been developed for automated analog synthesis are reviewed. The synthesis process is described. The major techniques employed by the tools are examined. They are knowledge-based hierarchical design, analytic design, and placement/routing. Critical design issues are identified.

Integrated-Circuit Analog Multiplexer

IEEE Transactions on Biomedical Engineering, 1970
An analog multiplexer which allows several data channels to share the available bandwidth of one channel of an analog tape recorder is described. The method involves demodulation by correlating with a separately recorded carrier. Inexpensive integrated circuits are the only active elements.

Symbolic analysis of analog integrated circuits

Proceedings Eleventh International Conference on VLSI Design, 2002
In this paper we describe a new approach to simplification of symbolic expressions obtained using symbolic simulators. We use a combination of matrix-based and flow-graph based technique to generate signal flowgraphs that have frequency-dependent edge weights.

Verification of Complex Analog Integrated Circuits

2007 6th IEEE Dallas Circuits and Systems Workshop on System-on-Chip, 2006
Functional complexity in analog, mixed-signal, and RF (A/RF) designs is increasing dramatically. Today?s simple A/RF functional block such as an RF receiver or power management unit can have hundreds to thousands of control bits. A/RF designs implement many modes of operation for different standards, power saving modes, and calibration.

A routing methodology for analog integrated circuits

1990 IEEE International Conference on Computer-Aided Design. Digest of Technical Papers, 2002
A general methodology for the design of the interconnections of analog circuits to meet high-level constraints on performance is described. In this approach, sensitivities of performance to parasitics are computed, and a set of bounding constraints for parasitics is determined.

Analog Integrated Circuit Optimization

2020
This chapter presents a novel telescopic operational transconductance amplifier (OTA) using the bulk-driven MOS technique. This circuit is optimized for ultra-low power applications such as biomedical devices. The proposed the bulk-driven fully differential telescopic OTA with very low threshold voltages is designed under ±0.9V supply voltage.

A Flexible Neural Analog Using Integrated Circuits

IEEE Transactions on Biomedical Engineering, 1970
An electronic neural analog is described which contains variable absolute and relative refractory periods, two time constants, and separate control of the ``accommodation'' to sub-threshold voltage changes and the ``adaptation'' produced by the occurrence of output pulses (spikes).
