Abstract

A ring oscillator comprising: a plurality of sub-feedback loops, each comprising a pair of serially connected inverters and a feedback inverter having its input coupled to the output of the pair of inverters and its output connected to the input of the pair of inverters, the pairs of inverters being connected in a ring, and a downstream inverter of each respective pair of inverters forming an upstream inverter of an immediately following pair of inverters.
