Abstract
A system for providing open-loop quadrature clock generation. The system is implemented by a ring oscillator structure that includes input inverters for receiving an input clock, forward direction loop inverters, backward direction loop inverters, one or more outputs, and cross-coupled latches connected between any two opposite nodes.
