    摘要： A frequency modulator includes a tuning circuit configured to determine a nominal gain characteristic of a digitally controlled oscillator (DCO) in a first mode, and to determine an actual gain characteristic of the DCO in a second mode using the nominal gain characteristic. The frequency modulator also comprises a modulation circuit comprising the DCO coupled to the tuning circuit, configured to modulate a frequency of a DCO output signal with a modulation signal input, and to scale the modulated DCO output signal based on the actual gain characteristic in the second mode to provide gain compensation and frequency modulation of the DCO. The tuning circuit may include a select switch to couple a minimal and maximal tuning word to the DCO in the first mode and an actual operating point word in the second mode to the DCO to determine the nominal gain characteristic.
