Abstract
A frequency synthesizer includes a frequency generator configured to generate a periodic output signal in response to a periodic input signal and a temperature-dependent code. A temperature sensor is provided, which is configured to generate a temperature measurement signal in response to detecting a temperature of at least a portion of the frequency synthesizer. A control circuit is provided, which is configured to generate the temperature-dependent code in response to the temperature measurement signal and a plurality of clocks having unequal frequencies. The control circuit can include a cascaded arrangement of an oversampled data converter and a digital filter, which are sequentially responsive to first and second ones of the plurality of clocks during generation of the periodic output signal by the frequency generator.
