Patent Searching and Data


Title:
CALIBRATION METHOD FOR CHIP HAVING PLURAL TEMPERATURE SENSITIVITY RING OSCILLATORS BY ONLY HAVING TO CALIBRATE ONE TSRO
Document Type and Number:
Japanese Patent JP2004219410
Kind Code:
A
Abstract:

To provide a temperature-sensitivity ring oscillator (TSRO) inside an integrated circuit.

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.
