Abstract
A voltage-boosted phase oscillator for driving a voltage multiplier comprises two intermeshed ring oscillators, each composed by an odd number of inverters connected in cascade through a closed loop and generating a normal phase and a voltage-boosted phase derived from the normal phase through a bootstrap circuit. The frequency of oscillation of both intermeshed ring oscillators is established by means of two similar RC networks common to both loops. The synchronization of the respective oscillations of the two rings is ensured by means of a plurality of SR flip-flops connected in cascade, formed by two NAND gates which, singularly, constitute as many inverters of the two rings. The oscillation and the arresting of the oscillation are controlled by means of a logic signal fed to a common input of a first pair of NAND gates which constitute respectively a first inverter of the relative ring oscillator and to a second input of which the phase produced by the relative ring oscillator is fed.
