S. Ozcan et al., Single resistance-controlled sinusoidal oscillators employing current differencing buffered amplifier, MICROELEC J, 31(3), 2000, pp. 169-174
The basic aim of this paper is to present several of a newly introduced cur
rent differencing buffered amplifier (CDBA)-based oscillator topologies ach
ieving orthogonal control of oscillation condition b and oscillation freque
ncy omega(0) with a reduced number of components. A single resistor is used
for adjusting their frequency, and further, this resistance is grounded, w
hich is important from the integration point of view. Taking these consider
ations into account they are very suitable for voltage-controlled oscillato
r (VCO) implementation. (C) 2000 Elsevier Science Ltd. All rights reserved.
