Abstract
In a recent paper the link between the Op Amp-based two integrator loop oscillators and current feedback operational amplifier (CFOA)-based oscillators is detected and clearly explained. It was found that one of the grounded capacitor two CFOA two integrator loop oscillators, however, was not related directly to any of the Op Amp oscillators. In this paper the origin of the two CFOA grounded capacitor oscillator is found to be the passive second-order low-pass filter. It is also found that the differential voltage current conveyor (DVCC) grounded passive element oscillator is generated from the same passive second-order low-pass filter. A new family of grounded capacitor oscillators using current conveyors (CCII) and inverting current conveyors (ICCII) which includes sixteen members is introduced. A second new family of grounded passive elements oscillators using CCII and ICCII which includes eight members is also introduced. A discussion and a comparison with some of the previously reported CCII oscillator circuits is also given at the end of the paper.
