Patent Images
1. An on die thermal sensor (ODTS), comprising:
- a bandgap unit configured to generate a first voltage including temperature information in response to a bandgap enable signal;
a tracking unit configured to track a voltage level of the first voltage generated from the bandgap unit in response to enabling of a tracking enable signal; and
a low power control unit configured to generate a pre-tracking enable signal and to generate the tracking enable signal in response to the generated pre-tracking enable signal, the low power control unit is configured to outputs the bandgap enable signal to the bandgap unit,wherein the tracking enable signal is configured to be disabled after a minimum tracking operation time of the tracking unit elapses.
