Abstract
A voltage controlled oscillator (VCO) circuit generates an output signal having a frequency which is dependent on a control voltage. A current is generated which is itself dependent on an amplitude of the VCO circuit. The generated current accordingly tracks, to an extent, the temperature behavior of the oscillator within the VCO circuit. The oscillator is driven by the sum of the generated current and a control current dependent on the control voltage. The control voltage may, for example, be generated by a phase lock loop (PLL).
