Abstract

The basic aim of this paper is to present several of a newly introduced current differencing buffered amplifier (CDBA)-based oscillator topologies achieving orthogonal control of oscillation condition b and oscillation frequency omega(0) with a reduced number of components. A single resistor is used for adjusting their frequency, and further, this resistance is grounded, which is important from the integration point of view. Taking these considerations into account they are very suitable for voltage-controlled oscillator (VCO) implementation. (C) 2000 Elsevier Science Ltd. All rights reserved.
