    Abstract: Several calibration techniques for a precision relaxation oscillator with temperature compensation produces a stable clock frequency over wide variations of ambient temperature. The calibration techniques provide for different methods of determining CTAT current, PTAT current or the ratio of PTAT current to CTAT current. The calibration techniques provide different methods for determining CTAT and PTAT calibration values and for setting CTAT and PTAT calibration select switches.
