High Precision Temp Sensor on TSMC CLN3E

The High Accuracy Thermometer is a highly integrated macro for monitoring temperature variation on- chip, allowing very high precision even in untrimmed usage. It consumes very little power even in operational mode, and leakage power only when measurement is complete. An additional voltage sample mode is included allowing for voltage monitoring. The block includes a simple-to-use digital interface that works with standard core and IO level power supplies. The macro uses core and thick-oxide devices.
