Short summary
Today's wireless transceivers are demanding for lowest power consumption to support long battery lifetime. These architectures utilize dutycycle schemes based on ultra-low-power (ULP) oscillators to reduce power consumption. These ULP oscillators are either using external components increasing the cost or they need calibration techniques to achieve absolute accuracy. This work presents an improved ULP calibration technique overcoming typical limitations of settling time and calibration accuracy.
