Abstract
A variable frequency oscillator device includes a first inverter stage that is designed to invert an input signal to generate a sawtooth signal by charging and discharging a capacitor using current sources that each provides a respective amount of current that is responsive to a control signal and to a dampening signal. A second inverter stage is designed to generate a first inverted signal from the sawtooth signal of the first inverter stage. A third inverter stage is designed to generate a second inverted signal from the first inverted signal, and dampen a signal transition rate for the first inverted signal based upon the control signal.
