Abstract
A device includes a sensor and an oscillator. The sensor provides a temperature-sensitive voltage. The oscillator includes a digital delay cell and an adjustment device. The adjustment device, based on the temperature-sensitive voltage, adjusts a delay of the digital delay cell, wherein the digital delay cell produces, based on the adjusted delay, a signal at an oscillation frequency.
