Abstract
An apparatus and method for determining temperature is disclosed. An ultrasonic signal is generated that propagates through a buffer and a portion of the signal is reflected at an interface. A time of flight is measured between generating the ultrasonic signal and detecting the reflected portion. The temperature is determined based on the time of flight of the reflected signal.
