About theoretical and practical aspects of current mode RC oscillators design

This paper addresses a group of constructive elements with which, (through adequate combinations) one can generate current mode RC oscillator transfer functions. Obviously this elements set is not unique. From the multitude of possible solutions only the solutions that accommodate the below conditions stand out: - the active elements can be easily produced in monolithic technology, - each oscillator must have two resistors or two capacitors connected to the mass. The latter requirement is very important for the oscillators with variable frequency. It was made RC oscillators and its transfer functions, and it was made a study of errors which affects maintaining gain oscillations and frequency oscillation. The paper point out the experimental results obtain through RC oscillators implementation with PA 630 current conveyors showing that the current mode oscillators appears to be an interesting approach from the perspective of the simplicity/performance compromise.
