Abstract
In accordance with an embodiment, a ring oscillator includes a plurality of stages coupled in a ring configuration, where stage of the plurality of stages has an input node coupled to an output node of a previous stage of the plurality of stages. Each stage of the plurality of stages includes: a ring oscillator transistor having a control node coupled to the input node, and a load path coupled to the output node; a direct injection circuit having a load path coupled between the control node of the ring oscillator transistor and the output node, and a control node coupled to a first oscillator input node; and a tail injection circuit having a load path coupled between the output node and a first power supply node, and a control node coupled to a second oscillator input node.
