Abstract
A ring oscillator includes a set of metal-oxide-semiconductor (MOS) complementary, inverting stages, wherein each stage includes a pair of cross-coupled CMOS NAND or NOR gates. The first and last stages are also cross-coupled, such that positive and negative output signals of the last stage are connected respectively to negative and positive input signals of the first stage.
