This article presents a new type of sine oscillator, discovered and studied at the Faculty of Electronics and Telecommunications in Timisoara. It analyzes the numerous theoretical and practical aspects that appear and signals its spectacular performances. The scheme of the new oscillator was introduced for the first time in Electronic Engineering, London, Febr. 1993. But here is presented the complete theory of the oscillator established after several years of research. The new sine oscillator is sure to have the best performancse of all known quartz-free oscillators.
Keywords: double simulation, electronic quartz, quadrature, sine oscillator
