A sine wave oscillator

A closed-loop oscillatory system, comprising an RC differentiator, a new type of an RC network and two transactors in cascade is described. For certain system conditions the circuit produces a sine wave oscillation whoso frequency is varied over a wide range from a very low to a high value. The main feature of the system is that the generation of a very low frequency oscillation is possible without incorporating a large value of the RC product. The frequency relation is derived and the results are presented in graphs.
