Chip temperature protection using delay lines |
摘要 |
A temperature protection device determines the operating temperature of an integrated circuit chip. The temperature monitor includes a delay line made up of serially connected delay cells. The propagation time of a signal through the delay cells is determined and this value is correlated to chip temperature. The chip temperature is compared to an operating range for the chip, and if the value is outside a predetermined range, an alert signal is produced.
