1. An integrated circuit comprising:

  • a first stage comprising a first plurality of transistor devices, wherein said first plurality of transistor devices are based on a first magnitude threshold voltage;

    a second stage comprising a second plurality of transistor devices, wherein said second plurality of transistor devices are based on a second magnitude threshold voltage;

    wherein said first magnitude threshold voltage is different in magnitude from said second magnitude threshold voltage;

    wherein said second stage is coupled to said first stage in a feedback configuration; and

    wherein said second stage comprises a frequency-voltage characteristic when combined in opposition with a frequency-voltage characteristic of said first stage produces a frequency-voltage characteristic that is more stable with respect to voltage over a range of frequencies than said frequency-voltage characteristic of said first stage.
