A Proportional-To-Absolute-Temperature (PTAT) current source is used for high-resolution temperature measurement. The PTAT current source is coupled to a capacitor for a fixed amount of time so as to charge the capacitor to a voltage which is proportional to the current applied to the capacitor, and...
