Abstract

See full text

A device including delay cells connected in series and in a feedback loop to provide a ring oscillator. At least one of the delay cells in the ring oscillator is a stacked gate delay cell that includes two or more PMOS transistors having first drain/source paths connected in series to each other and having first gates connected to each other and two or more NMOS transistors having second drain/source paths connected in series to each other and to the first drain/source paths and having second gates connected to each other and to the first gates.
