1. A method of compensating for a non-linear region of high gain in a ring oscillator, said method comprising:

  • representing the metal layers forming gates and various stray capacitance as a capacitor to be charged and discharged at an oscillating frequency for said oscillator;

    charging and discharging said capacitor by a variable current supplied through a series circuit by a current starved inverter; and

    compensating for said high gain and non-linear region by an anti high-gain circuit having a source of fixed charging and discharging current in parallel with said variable current supplied by said current starved inverter.
