CALIBRATION METHOD FOR CHIP HAVING PLURAL TEMPERATURE SENSITIVITY RING OSCILLATORS BY ONLY HAVING TO CALIBRATE ONE TSRO

摘要

PROBLEM TO BE SOLVED: To provide a temperature-sensitivity ring oscillator (TSRO) inside an integrated circuit.;SOLUTION: A temperature measuring instrument, such as a thermal resistor, is in proximity to the TSRO, and substantially the same temperature is shared. A memory can be used for storing data, which are function of the outputs of the TSRO and the temperature measuring instrument.;COPYRIGHT: (C)2004,JPO&NCIPI
