Nonlinear time-domain macromodeling of OTA circuits
(Institute of Electrical and Electronics Engineers, 1989)
The authors present an accurate nonlinear macromodel of the operational transconductance amplifier (OTA) which is suitable for the transient simulation of OTA-based CMOS analog integrated circuits. As compared to device-level ...

Generation and design of sinusoidal oscillators using OTAS
(Institute of Electrical and Electronics Engineers, 1988)
The design of voltage-controlled oscillators (VCOs) using operational transconductance amplifiers (OTAs) is discussed. Several oscillator structures are proposed. They use only OTAs and capacitors (OTA-C) and are very ...

Serial architecture for fuzzy controllers: hardware implementation using analog/digital VLSI techniques
(1992)
A new architecture is presented for the implementation of fuzzy systems using analog-digital techniques. This architecture is directed towards allowing the implementation of many rules on the same chip, including the fuzzy ...

Accurate design of analog CNN in CMOS digital technologies
(Institute of Electrical and Electronics Engineers, 1990)
Explores the design of cellular neural networks (CNN) by using sampled-data analog current-mode techniques which neither requires capacitors nor resistors but just MOS transistors. The feature makes the proposed technique ...

Modular analog continuous-time VLSI neural networks with on chip hebbian learning and analog storage
(Institute of Electrical and Electronics Engineers, 1992)
A modular analog circuit design approach for hardware implementations of neural networks is presented. This approach is based on the use of small transconductance multipliers as the main component, and is therefore called ...

A Chaotic Switched-Capacitor Circuit for 1/f Noise Generation
(Institute of Electrical and Electronics Engineers, 1992)
A switched-capacitor circuit is reported for the generation of 1 / fYnoise. The circuit is described by a chaotic first-order piecewise-finear discrete map which yields a hopping transition between regions of chaotic motions ...

State merging and state splitting via state assignment: a new FSM synthesis algorithm
(Institute of Electrical and Electronics Engineers, 1994)
The authors describe a state assignment algorithm for FSMs which produces an assignment of non-necessarily distinct, and eventually, incompletely specified codes. In this new approach, state-reduction and state assignment ...
