Abstract
A temperature sensor configured to, after a predetermined number of stop counting assertions, determine the temperature dependent voltage and thus the temperature at the output of a counter. During a calibration phase, when a counter value is not equal to a test counter value in a pulse generator circuit, capacitance of the temperature sensor is adjusted until the counter value is equal to the test counter value.
