On the Design of Voltage-Controlled Sinusoidal Oscillators Using OTA's
(Institute of Electrical and Electronics Engineers, 1990)
A unified systematic approach to the design of voltage-controlled oscillators using only operational transconductance amplifiers (OTA's) and capacitors is discussed in this paper. Two classical oscillator models, i.e., ...

Hysteresis based neural oscillators for VLSI implementations
(Institute of Electrical and Electronics Engineers, 1991)
The actual tendency in most of the work that is being done in VLSI neural network research is to use the simplest possible models to perform the desired tasks. This yields to the use of sigmoidal type neurons that have ...

CMOS analog neural network systems based on oscillatory neurons
(Institute of Electrical and Electronics Engineers, 1992)
This paper addresses the design of two neural network systems based on the use of pulsing neurons. Each neuron is built as a simple voltage controlled oscillator (VCO) whose control voltage makes the circuit to oscillate ...

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 ...

Frequency tuning loop for VCOs
(Institute of Electrical and Electronics Engineers, 1991)
A frequency tuning circuit is introduced for VCOs (voltage-controlled oscillators) so that the final relationship between oscillating frequency and input control voltage is fixed and independent of nonidealities. This ...
