Abstract
An oscillator circuit on a chip with a single I/O node whose output generally corresponds to a performance level of the IC chip. The single I/O node provides an easy access and testing point for evaluating chip performance. The I/O node is used for coupling to the oscillator circuit, and for activating and monitoring its oscillating output signal. The single I/O node may be accessed at the wafer level, after packaging, or in the field.
