An integrated circuit ( ) is disclosed comprising a fundamental frequency oscillator comprising a reference node ( ) whose voltage varies between a high threshold and a low threshold. The fundamental frequency oscillator is operable to generate a first output at the fundamental frequency on a first output node ( ). The integrated circuit ( ) also comprises a circuit (C ) coupled to the reference node. The circuit (C ) is operable to sense the voltage at the reference node ( ), to determine when the voltage exceeds an intermediate threshold between the high threshold and the low threshold, and to generate a second output in response to the determination. The integrated circuit ( ) also comprises logic ( ) coupled to the circuit (C ) and load circuitry ( ) coupled to the logic ( ). The logic ( ) is operable to generate an output signal at an output frequency greater than the fundamental frequency in response to the second output and the first output.
