A system and method is provided for controlling frequency of an oscillator. The system includes two or more temperature sensing circuits configured to generate temperature sensing signals corresponding to temperatures obtained by the two or more temperature sensing circuits. The system also includes a reference signal generation circuit configured to generate a reference signal and a first curve function generation circuit coupled to the two or more temperature sensing circuits and the reference signal generation circuit. The first curve function generation circuit is configured to provide two or more curve-generating signals based on the temperature sensing signals and the reference signal. The system further includes a summing circuit coupled to the first curve function generation circuit. The summing circuit is configured to provide, based on the two or more curve-generating signals, a first signal for controlling the frequency of the oscillator. |
