Abstract
A digital temperature monitor (DTM ( ) includes a proportional-to-absolute temperature (PTAT) sensor ( ) and reference circuit ( ) coupled to the inputs of a comparator ( ). The DTM ( ) monitors the temperature of adjacent and/or proximate integrated circuitry. The method includes the steps of providing a reference signal to the comparator ( ), increasing the reference signal voltage, and determining the temperature of an integrated circuit by determining when the reference signal is greater than the PTAT sensor ( ) output voltage. The DTM ( ) may be implemented as part of a hard-disk drive preamplifier circuit ( ).
