Calibration unit for calibrating an oscillator, oscillator arrangement and method for calibrating an oscillator

Abstract:

Disclosed is a calibration unit for calibrating an oscillator of a device comprises a counting and comparing unit and a control circuit. The counting and comparing unit is configured to determine a number of periods of a clock signal lying between a starting instance and an ending instance. Therein, the clock signal is generated by the oscillator. The counting and comparing unit is further configured to determine a deviation of the number of periods from a reference number. The control circuit is configured to adjust the oscillator depending on the deviation.
