摘要： An electronic device is equipped with an oscillator interface to be coupled to an oscillator crystal of an oscillator element. The electronic device includes an oscillator circuit which is coupled to the oscillator interface and generates an oscillator signal. The electronic device is further provided with a temperature measurement interface to be coupled to a temperature sensor of the oscillator element so as to receive the temperature signal. For accomplishing temperature compensation, the electronic device is provided with a measurement controller coupled to the measurement interface and configured to measure a first value of the temperature signal at a first point of time and a second value of the temperature signal at a second point of time. A frequency drift estimator is provided so as to estimate a frequency drift of the oscillator signal on the basis of the first value of the temperature signal and a second value of the temperature signal. By means of a compensation logic, a frequency compensation signal for the oscillator circuit is generated on the basis of the estimated frequency drift.

摘要： A semiconductor device includes an operation unit (CPU) provided in a semiconductor chip and a temperature sensor (TS) that measures a temperature of the semiconductor chip. The semiconductor device compares a measured temperature (Ta) measured by the temperature sensor (TS) with a predetermined reference temperature (Tref). When the measured temperature (Ta) is higher than the reference temperature (Tref), the semiconductor device switches a frequency of an operation clock to be supplied to the operation unit (CPU) from a first frequency to a second frequency higher than the first frequency.
