Abstract
The present invention provides an integrated circuit VLSI temperature system for the calibration of threshold temperatures. A temperature sensitive ring oscillator (TSRO) generates a TSRO calibration parameter. A memory is employable to store the TSRO calibration parameter. A module is employable to determine a threshold TSRO oscillation frequency from the TSRO calibration parameter. A memory is employable for storing at least one threshold TSRO oscillation frequency.
