Abstract
An oscillator utilizes two current sources that have the same temperature and VDD dependency so they generate the same current in changing conditions. Therefore, there is very low VT dependency. The resistor and fringe capacitor temperature coefficient are very low and opposite so they compensate for each other. A comparator with a short period of operation also minimizes VT dependency.
