TRANSFORMATION OF SINUSOIDAL OSCILLATORS USING UNIVERSAL ACTIVE ELEMENTS

A procedure for synthesising sinusoidal oscillators using finite-gain controlled sources is proposed. Based on some fundamental theorems of network theory, this method permits the generation of a set of functio nally equivalent oscillators with different controlled sources. In thi s way synthesis and design-specific methods to each one are not necess ary. In demonstrating feasibility, the operational floating conveyor h as been used as the active element to implement different types of con trolled sources. Design criteria and experimental results are given.
