Stability Analysis of New High-Stability Square-Wave Generator

An original solution of the system for generating high stable frequency of square-wave oscillation using an RC bridge network as the timing element is given. The high stability of the system is based on the property of self-compensation. With respect to the action of external factors (voltage supply or temperature changes), the system provides a correlation between the variation in two neighboring half-periods, so the prolongation in one half-period affects the shortening of the next with an outstanding tendency to keep the duration of the oscillation period unchanged. In this way the oscillation frequency stability is reduced to the passive RC bridge element and stability of an order 10-4 in practical solutions can be achieved.
