Abstract
Systems and methods of a temperature compensated real-time clock are disclosed. The systems and methods can include measuring a temperature with a temperature sensor, detecting a temperature dependent frequency from an oscillator, inputting the temperature and determining a temperature estimate for the oscillator with an infinite impulse response filter, and determining a compensation factor, for the oscillator.
