More Information
Summary:An integrated circuit includes a circuit unit and an oscillating signal-generating assembly. The circuit unit includes a plurality of first cells. The oscillating signal-generating assembly is configured to generate different oscillating signals and includes a ring oscillator, a signal line, and a switching unit. The ring oscillator includes a plurality of second cells, each of which has an output terminal. The second cells are of the same type as the first cells. The signal line is configured to receive the different oscillating signals. The switching unit is coupled between the ring oscillator and the signal line and is configured to selectively couple the output terminals of the second cells to the signal line. A timing characteristic of a cell of the same type as the first cells can be estimated from the different oscillating signals.
