Abstract
A tunable oscillator for producing an output signal includes an input for receiving a first voltage that is a function of the output signal, a controllable oscillator, and a voltage element that produces a second voltage and has a first leak current. The controllable oscillator produces the output signal based upon the first and second voltages, and the first leak current causes the second voltage to fluctuate. The tunable oscillator also includes a current generator operatively coupled with the input. The current generator produces a generator current that is a function of the first voltage, where the first voltage is responsive to fluctuations in the second voltage. The generator current compensates for the fluctuations in the second voltage.
