A method and apparatus for enhancing the stability of an oscillator circuit by generating a frequency comb in a non-linear resonator member in response to a drive frequency, the oscillator circuit including a voltage-controlled oscillator locked to a particular tooth of the frequency comb generated by the non-linear resonator member at the drive frequency for which the voltage-controlled oscillator is locked to a particular tooth of the frequency comb generated by the non-linear resonator member at the drive frequency. The absolute value of the first derivative of the driving frequency to the comb frequency is greater than 1, and wherein the second voltage-controlled oscillator is coupled with a phase-locked loop circuit that controls the locking of the second voltage-controlled oscillator to the particular tooth of the frequency comb. 一种用于通过响应于驱动频率而在非线性谐振器构件中生成频率梳来增强振荡器电路的稳定性的方法和设备，振荡器电路包括压控振荡器，压控振荡器被锁定到由非线性谐振器构件在驱动频率下产生的频率梳的特定齿，对于驱动频率，驱动频率对所述梳频率的一阶导数的绝对值大于1，并且其中第二压控振荡器与锁相环电路耦接，锁相环电路控制第二压控振荡器到频率梳的所述特定齿的锁定。
